    Guide to Online Submission

    All manuscripts, including letters to the editor, replies to the editor, and correspondence, must be submitted online via the Elsevier Editorial System (EES) web site. Go to http://ees.elsevier.com/jcrs and select "log in." You will immediately see the screen "Elsevier Editorial System Log-In." You will be asked for your username and password. If you have not yet registered, you will see a place to do so. If you are registered, type in your username and password and click on author login. You will be guided step-by-step through the creation and uploading of various files including the manuscript, synopsis, figures, and tables. Once the uploading is complete, the system will automatically generate an electronic (PDF) proof, which is used for reviewing. All correspondence regarding submitted manuscripts will be handled via e-mail through EES.

    The article must be in 12-point type, double-spaced, with 1-inch margins (with all pages numbered consecutively). It should follow the general instructions for authors about content and style. The text should use the wrap-around-end-of-line feature; ie, returns at the end of paragraphs only. Place 2 returns after every element such as title, headings, paragraph. Please do NOT use a citation generaling program (e.g., End Notes), or any automatically generated numbering or bulleting systems or hidden text (eg, for footnotes, lists).

    See the JCRS Information for Authors for descriptions of the content and format of each type of article (full length article, case report, technique, review/update, letter, correspondence). Manuscripts with incorrect formating will be returned unreviewed for modifications.

    Files Required for New Submission

    The following files must be included with each submission. The files should be in the following order:

    Manuscript File (with the Following Items)

    1. Title page: The title of the paper should be short and specific. A short running head should also be provided. The title page should include the following: (1) each author's full name (ie, first name, middle initial if used, and last name) and no more than 4 degrees (only first 4 will be published); (2) affiliation of each author; (3) if presented at a meeting, provide the exact name of meeting and city, country, and month and year of the meeting; (4) sources of public and private financial support, including organization's name, city, and country; (5) statement about the authors' financial or proprietary interest in a product, method, or material, or lack thereof; and (6) name and address of author to receive reprint requests.

    2. Abstract: This should follow the title page.

    3. Text of the article, including the references. If there are figures, the figure legends must follow the references. (The figures themselves go in a separate file.)

    Synopsis File

    A synopsis is required for full-length articles and review/date articles, but not for case reports or techniques. The synopsis goes in the table of contents. It should be no more than 30 words and should describe the main finding(s) of the paper and the significance but should not duplicate the abstract conclusion.

    Figure File

    Each figure should be attached in a separate file. (All figures legends should be in the manuscript file, not with the figure itself.) The preferred formats are TIF or EPS (jpg and gif formats are more suitable for viewing on the Web, not for print) at the standard resolutions (ie, 300 dpi for photos - final size in print journal; 1200 dpi for line art).

    Table File

    All tables can be in 1 file. Include the legends with the tables.

    Video File

    Preferred video files are MPEG-4 video/MP3 audio. If another format file is used, the typesetter will have to convert it to .mpg format so it can be accepted by the online platforms.

    Elsevier recommends 10 MB as the optimal size as this ensures that end users are able to download and view files in a reasonable timeframe. Elsevier can handle up to 160 MB but anything more than that will have to be compressed for conversion as a zip file, meaning the video will be online as a .zip file.


    REMINDERS FOR SUBMITTING A NEW MANUSCRIPT

    Abstract is required in 2 places: at the beginning of the submission process, where requested; in the manuscript file, following the title page.

    Techniques and case reports: 150-word descriptive abstract
    Full length articles: 250-word structured abstract

    Text must be submitted as a Word (.doc) file, not as a PDF.

    Figures and tables should not be embedded in the text; they must be submitted as separate figure and table files.

    Figure legends should be included in the manuscript file, following the references.

    Synopsis (required for full length articles and review/update articles) should be no more than 30 words.


    Files Required for Revised Submission

    The following files must be included, in the order given, with a revised submission:

    Revision Notes

    Indicate the specific changes that were made to the submission.

    Revised Manuscript with Highlighted Changes

    Highlight all the changes that were made to the text.

    Revised Manuscript (without highlighting)

    Do not include any highlighting or notations in this file as it is the one that will be used for production purposes.

    Synopsis File

    Include the synopsis even if it is the same as the one in the first submission.

    Figure File

    Attach the figures even if they are the same as the ones in the new submission. (The figure legends should be in the revised manuscript files.)

    Table File

    Attach the tables with their legends even if they are the same as those in the new submission.

    Technical Support

    If you need technical support with the online system, please contact authorsupport@elsevier.com.

    Information for Authors

    The Journal of Cataract & Refractive Surgery is produced by the American Society of Cataract and Refractive Surgery and the European Society of Cataract and Refractive Surgeons.

    The Journal of Cataract & Refractive Surgery is published by Elsevier Science Inc., New York, NY, USA.

    Submission Information

    Manuscripts should be submitted via the online submission system at www.jcrsjournal.org. See the Guide to Online Submission for specific submission instructions.

    Manuscripts submitted to the journal must be original material that has not been published or accepted for publication, in whole or in part, in English or in another language, elsewhere. All papers are submitted to an international panel for peer review. Criteria for editorial review include suitability of subject matter, originality of content contribution to the field, and timeliness.

    Manuscript Preparation

    The title of the paper should be short and specific. A short running head should also be provided.

    The title page should include the following: (1) each author's full name (ie, first name, middle initial if used, and last name) and highest degree; (2) city, state, and country in which work was carried out; (3) if presented at a meeting, name of the organization, city, country, and exact date of presentation; (4) sources of public and private financial support, including organization's name, city, and country; (5) name and address of author to receive reprint requests; (6) statement about the authors' proprietary or financial interest in a product or lack thereof.

    Credit for authorship requires substantial contributions to the area enumerated in the Uniform Requirements for Manuscripts Submitted to Biomedical Journals (www.icmje.org). The number of authors is limited to 8 for a single-center study and 12 for a multi-center study. If more authors are included, each must sign a statement confirming that he or she fulfills the authorship criteria. No more than 8 and 12 authors, respectively, will be listed under the title; other names will appear in a footnote.

    Groups of people who have contributed materially to the paper but do not meet the authorship criteria will be listed in an appendix (eg, Clinical Investigators, Participating Investigators, Study Group).

    References and legends for figures should be double-spaced and should follow the text of the paper. There is a limit of 30 references in clinical studies.

    All papers are subject to revision to conform with terminology and style used by the journal. Authors should adhere to accepted English usage and syntax. Suggested references: American Medical Association Manual of Style, 9th ed. Baltimore, MD, Williams & Wilkins, 1998; Scientific Style and Format; the CBE Manual for Authors, Editors, and Publishers, 6th ed. New York, NY, Cambridge University Press, 1994.

    Content

    For both clinical/laboratory studies and techniques, JCRS now requires the inclusion of a short section that indicates the value of the paper relative to the existing literature. The section should be added at the conclusion of the text just before the references. Using the following format (1-2 bullet points per statement), please summarize what was known about the topic before the paper and what the paper adds. Note that in the following example, the "What Was Known" section ends with a clear statement about the gap in knowledge that the current paper attempts to address.

    WHAT WAS KNOWN
    • In phakic eyes prior to endothelial transplantation, it is common practice to first remove the patient's crystallinelens, even in the absence of a cataract. This measure, while believed to facilitate DSEK/DSAEK surgery, and/orto reduce subsequent cataract formation, has not been studied in DMEK patients.

    WHAT THIS PAPER ADDS
    • Descemet membrane endothelial keratoplasty can be easily performed in phakic eyes, and leaving the crystalline lens in-situ rarely results in secondary cataract formation.
    • As better overall optical quality may be achieved in phakic DMEK eyes when accommodative function is spared, it is worth considering leaving the (clear) crystalline lens in situ prior to DMEK.

    "What This Paper Adds" should not simply restate the results. Rather, it should specifically highlight the novelty of the findings relative to prior studies or reports. It should also not repeat the synopsis text, which is a brief summary of the results and conclusions of the paper.

    Clinical Studies

    Reports of clinical studies should be prefaced by a 250-word structured abstract. The structured abstract should have the following sections:

    Purpose: Indicate the question that the study answers or the hypothesis that it tests.

    Setting: Indicate where the study took place; this enables readers to assess the study's applicability to their practice.

    Design: Describe the study design, indicating randomization and masking and masking and whether the data collection was retrospective or prospective.

    Methods: Identify the patients, including selection procedures, inclusion and exclusion criteria. Indicate the intervention procedures and the outcome measurements.

    Results: Present the outcomes and measurements. Data should include the level of statistical significance.

    Conclusions: State the conclusions and their clinical pertinence.

    Reports of clinical studies should include a synopsis for the table of contents. The synopsis should be no more than 30 words and should describe the main finding of the paper but not duplicate the abstract conclusion.

    The text must follow a standard format: introduction, materials and methods used, presentation of results, and discussion. Conclusions can be incorporated into the discussion or placed in a separate section.

    The description of materials and methods must be explicit enough that the study can be repeated by others; results must be reproducible. If a method has been published in an English language, peer-reviewed journal, a reference is adequate. Use generic or descriptive nomenclature for drugs and instruments, with the brand name in parentheses.

    In clinical studies involving experimental investigations, the manuscript must state that informed consent was obtained from all participants and that the study was reviewed by an ethics committee or review board (IRB) or that no IRB approval was required.

    In experimental studies using animals, the manuscript must describe the care of the animals and indicate ethics committee or IRB approval. These studies should conform to principles of animal maintenance such as those described in the Association for Research in Vision and Ophthalmology Statement for Use of Animals in Ophthalmic and Vision Research.

    Statistical methods should be defined; any not in common use should be described in detail or supported by references. General guidelines on the use of statistical methods and specific recommendations on statistical estimation and significance are given under Statistical Guidelines.

    Visual acuity should be reported in Snellen format for means and ranges. Mean visual acuity should be determined by calculating the geometric mean with standard deviation stated in logMAR format (Holladay JT, Prager TC. Mean visual acuity. Am J Ophthalmol 1991; 111:372-374 )

    In the results section, avoid redundant data presentation. As a rule, information stated in the text should not be repeated in the tables. Graphs and tables should be used for detailed lists of findings. Note: If reporting preoperative and postoperative data for more than 3 factors, data should be presented in a table. If too many data are presented in the text, the article will be returned to the author for revision.

    Techniques

    Articles that describe a technique should be prefaced by a 150-word descriptive abstract. The text should include an introduction, description of the technique, discussion, and references. If the technique was used in patients, the results should be presented as a subsection of the technique section; in a technique article, the emphasis should be on the technique, not on the clinical results.

    Although not required, inclusion of a video is encourages. All technique videos will become part of a Technique Video Collection on the JCRS Web site. See "Format for Video" section for a description of the formats that are accepted.

    The video must not include the device/product names, manufacturer, or surgeon name, must be cited in the text, and a legend that fully describes the video should be included with the figure legends. The video and legend will appear on the ASCRS and JCRS web sites.

    The purpose of the video is to supplement but not replace the description of the technique in the article itself. Therefore, the manuscript should be self-contained; ie, the reader should be able to understand and repeat the technique based on the text and figures in the manuscript alone. The article and video will be reviewed according to the journal's standard review process.

    Format for Video: Preferred video files are MPEG-4 video/MP3 audio. If another format file is used, the typesetter will have to convert it to .mpg format so it can be accepted by the online platforms.

    Elsevier recommends 10 MB as the optimal size as this ensures that end users are able to download and view files in a reasonable timeframe. Elsevier can handle up to 160 MB but anything more than that will have to be compressed for conversion as a zip file, meaning the video will be online as a .zip file.

    Case Report

    Case reports should be prefaced by a 150-word descriptive abstract. The text should include 4 primary sections: introduction, case report(s), discussion, and references.

    Correspondence

    Short reports do not require an abstract or a structured format. They should not exceed 700 words and can have no more than 8 references and 2 figures or tables. They should not include more than 4 authors. A title page or cover sheet must provide full names of all authors, a financial interest statement, and the postal and email addresses of the corresponding author. Short reports are reviewed and are subject to editing.

    Letters to the Editor

    Letters about recently published JCRS articles are encouraged and should be submitted within 8 weeks of the article's publication. A letter should have a title that indicates the focus of the letter; ie, not the same as the title of the article. The text should not exceed 500 words and can have no more than 5 references and 1 figure or table. Gratuitous comments (eg, "We congratulate . . . on their excellent work") should be avoided. A title page or cover sheet must provide full names of all authors, a financial interest statement, and the postal and email addresses of the corresponding author. Letters are reviewed by the journal editors and are subject to editing. The authors of the article will be given an opportunity to reply.

    References

    Papers are judged in part on the appropriateness of the references cited, and references are expected to reflect the most current literature on the subject.

    General Guidelines

    1. All sources must be acknowledged by a reference, and all references must be cited in the text.
    2. Use caution when citing review papers, editorials, and correspondences. They are appropriate to cite when novel concepts, data, models or meta-analyses are presented, but primary sources should always take precedence.
    3. Don't overlook papers with negative results. First consider whether sample sizes were adequate and methods were sound, and if so, such results may be important to address.
    4. Use more specific callout text to the literature. Be sure the reader knows why the source is critical to the current argument. If a reference does not have a clear connection to the argument, perhaps it can be omitted.
    5. Include the citation immediately after the clause or phrase that calls on it. Clustering references at the end of a sentence with a string of callouts dissociates references from the their text.
    6. Avoid listing references for the sake of showing the number of manuscripts available on a topic. Such lists are often cited at the end of an introductory statement such as "LASIK is the most commonly performed refractive surgical procedure" to efficiently acknowledge a body of generally related work. A problem with this practice is that it increases the number of citations dramatically, inflates the impact of each paper in the list, and at the same time dilutes the impact of other cited papers that were chosen on the basis of specific impact. An alternate approach is to indicate that a search was performed, specify the search engine and key word(s) used, and report the number of relevant articles that were identified. In general, though, such statements rarely require references.
    7. Scrutinize any self-citations carefully and subject them to the same criteria used for other references. Awareness of the omnipresent temptation for promoting our own work or that of close colleagues can help keep these forces in check.

    Formats

    JCRS uses a 2-part reference list: REFERENCES for peer-reviewed material and published texts, which should appear in the text of the paper as superscript numbers, and OTHER CITED MATERIAL for non-peer-reviewed material (web sites, abstracts, meeting presentations, drug/manufacturer material), which should appear in the text as superscript letters. This change avoids cumbersome text insertions citing non-peer-reviewed sources.

    Peer-Reviewed Material

    The list of references should be numbered in the order that the references are cited in the text. Journal names must be abbreviated according to the form used by Index Medicus. All authors should be listed.

    Other Cited Material

    Non-peer-reviewed material includes manuscripts not yet in press, abstracts, web sites, meeting presentations, articles in news magazines, personal communications, and drug/manufacturer material. These items should be cited alphabetically in the text as superscripts and in an "Other Cited Material" list following the peer-reviewed reference list.

    Video/Computer Graphics

    An original, edited CD-ROM in IBM compatible PC format will be the standard format for submission of videos and computer graphics (ie, slide presentations with or without animation). Journal of Cataract & Refractive Surgery (JCRS) will not edit any video or computer graphics, but reviewers, following the usual policy with illustrations, may suggest changes in the video or computer graphic. A sound track is highly recommended. Maximal cumulative length of videos or computer graphics is 8 minutes, and may be divided into several smaller clips not to exceed 8 minutes in total. If the video or animation is divided into several clips, each clip should be identified at the beginning of the section and on the CD-ROM, eg, Video Clip 1 or Graphic 1. Several videos/graphics may be on the same CD-ROM, but if they are separate clips, the separation must be clearly indicated. Concise legends (typed on a separate page) must accompany each video clip or computer graphic presentation.

    The following formats for video will be accepted: MPEG-1 or MPEG-2 (.mpg), Quicktime (.mov), Audio/Video Interface (.avi) or Compuserve GIF (.gif). Please contact the publisher about the use of other formats. A graphic will be used to indicate the location of a video clip or computer graphic. Videos/computer graphics for accepted manuscripts will not be returned. Videos and computer graphics will not be accepted separately from a manuscript that has been rejected. If the article is accepted for publication, the video will be digitized and archived on the JCRS website (http://www.jcrsjournal.org). The location of the video on the Web will be linked in the online version of the article. Reminder: Videos must not include the device Mdash; product name, manufacturer, or surgeon name.

    Statistical Guidelines

    To ensure meaningful statistical analysis of the study results, authors should consider the following questions:

    1. Was the source of subjects satisfactorily stated?
    2. Were concurrent controls used (as opposed to historical controls)?
    3. Were the treatments well defined?
    4. Was random allocation to treatment used?
    5. Was the randomization method described?
    6. Was the duration of post treatment follow-up satisfactory (at least 6 months)?

    Conduct of Study

    7. Were the treatment and control groups comparable with relevant measures?
    8. Did a high proportion of subjects achieve adequate follow-up?
    9. Were the dropouts characterized by treatment received?
    10. Were the side effects of treatment reported?

    Analysis and Presentation

    11. Was there a statement adequately describing or referencing all statistical procedures used?
    12. Were the statistical analyses appropriate?
    13. Were confidence intervals given for the main results?
    14. Was the level of significance stated for outcomes that were reported as significant?
    15. Was the reported level of significance corrected for the number of statistical analyses that were performed?
    16. When the null hypothesis was accepted (no difference between experimental groups), was the statistical power of the study calculated and reported?
    17. Was the conclusion justified by the statistical analysis?

    Alterations

    If authors make extensive changes to the text or the figures at the production stage (on page proofs), the journal reserves the right to charge the cost of the changes to the authors. No charge will be made for correcting errors made during the editorial process or by the printer.

    Recommendations

    Manuscripts from non-English-speaking countries should be reviewed and edited by someone proficient in the use of English.

    Study design should be reviewed by a methodologist.

    Reprints

    The senior author of each article will receive a reprint order form, which must be sent to the publisher at the time the page proofs are returned.

    Submission Checklist

    1. Complete title page (including acknowledgment of financial and proprietary interests and public and private support (if any)
    2. Structured abstract (for clinical articles)
    3. Descriptive abstract (for techniques, case reports)
    4. Synopsis of article (for clinical articles)
    5. Acknowledgment of financial and proprietary interests
    6. Acknowledgment of public and private support

    Manuscripts will not be reviewed until all these items have been submitted.

    Submission Information

    New manuscripts should be submitted through the JCRS submission and review web site (http://ees.elsevier.com/jcrs). See Guide for Online Submission for an explanation of the files required for a new manuscript. Once the submission files are uploaded, the system automatically generates an electronic (PDF) proof, which is used for reviewing.
