Manuscripts are evaluated on the basis that they present new insights to the investigated topic, are likely to contribute to a research progress. It is understood that all authors listed on a manuscript have agreed to its submission. The signature of the corresponding author on the letter of submission signifies that these conditions have been fulfilled. Received manuscripts are first examined by the Editors of Klinika Oczna. Manuscripts with insufficient priority for publication are rejected promptly. Incomplete packages or manuscripts not prepared in the advised style will be sent back to authors without scientific review. The authors are notified with the reference number upon manuscript registration at the Editorial Office. This journal operates a single-blind review process. All contributions will be initially assessed by the editor for suitability for the journal. Papers deemed suitable are then typically sent to a minimum of two independent expert reviewers to assess the scientific quality of the paper. The Editor is responsible for the final decision regarding acceptance or rejection of articles. The Editor’s decision is final.

Materials taken from other sources must be accompanied by a written statement from both author and publisher giving permission to Klinika Oczna for reproduction. Obtain permission in writing from at least one author of papers still in press, unpublished data, and personal communications.

All pages, along with bibliography, figures, captions and tables should be numbered.


The paper should carry a structured abstract not exceeding 250 words. For original article it should consist of four paragraphs labeled: Aim, Material and Methods, Results, Conclusions. Each of them should briefly describe, the purpose of the study, how the investigation was performed, the most important results and the principal conclusion that authors draw from the results. For case reports and review articles the abstract should provide a background for the described subject as well as the main teaching points. Only standard abbreviations should be used. However, the abstract and the paper's title should not contain any abbreviations. When using an abbreviated term for the first time, the full name should be given followed by the abbreviation in parentheses (this requirement does not apply to units of measurements).

Key words
Please provide a 3-6 key words (MeSH), using American spelling and avoiding general and plural terms and multiple concepts (avoid, for example, ‘ and’ , ‘ of’ ). Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible. These key words will be used for indexing purposes.

Article structure
1. Introduction should contain scientific rationale and the aim of the study or (in the case of a review) the purpose of the article.

2. Material and methods should clearly describe the selection of observational or experimental subjects, including controls, such as age, sex, inclusion and exclusion criteria, (the circumstances for rejection from the study should be clearly defined), and the randomization and masking (blinding) methods. The protocol for data acquisition, procedures, investigated parameters, methods of measurements, and apparatus used should be described in sufficient detail to allow other scientists to reproduce the results. Name and references for the established methods should be given. References and brief description should be provided for methods that have been published but are not well known, whereas new or substantially modified methods should be described in detail. The reasons for using them should be provided, along with the evaluation of their limitations. Drugs and other chemicals should be precisely identified, including generic name, dose, and route of administration. The statistical methods should be described in detail to enable verification of the reported results. Provide information on patient informed consent. Studies on patients and volunteers require informed consent documented in the text of the manuscript. Where there is any unavoidable risk of breach of privacy (eg, in a clinical photograph or in case details), the patient's written consent to publication must be obtained and a copy provided to the journal. Information on approval by a Local Ethics Committee should also be provided.

3 Results should concisely and reasonably summarize the findings. Restrict tables and figures to the number needed to explain the argument of the paper and assess its support. Do not duplicate data in graphs and tables. Give numbers of observation and report exclusions or losses to observation such as dropouts from a clinical trial. Report treatment complications. The results should be presented in a logical sequence in the text, tables, and illustrations. Do not repeat in the text all the data from the tables or graphs. Emphasize only the important observations.

4. Discussion should deal only with new and/or important aspects of the study. Do not repeat in detail data or other material from the Background or the Results section. Include in the Discussion the implications of the findings and their limitations, including implications for future research. The discussion should address the results of other investigations, especially those quoted in the text.

5. Conclusions should be linked with the goals of the study. State new hypotheses when warranted. Include recommendations when appropriate. Unqualified statements and conclusions not completely supported by the obtained data should be avoided.

6. Acknowledgements. List all contributors who do not meet the criteria for authorship, such as technical assistants, writing assistants, or department head, who provided only general support. Financial and other material support should be disclosed and acknowledged.


Abbreviations that are unavoidable must be defined twice: (1) at their first mention in the Abstract and (2) at their first mention in the remaining part of the article. Ensure consistency of abbreviations throughout the article.


Follow internationally accepted rules and conventions: use the international system of units (SI). If other units are mentioned, please give their equivalent in SI.
