Special Issue Information

Dear Colleagues,

Corneal surgery and treatments have become an important addition to the ophthalmic procedure armamentarium in clinical practice, with corneal transplantation being the most performed transplant worldwide. Also, the latest advances in corneal surgery, including the use of new biomaterials and novel techniques such as laser platforms, have provided ophthalmologists with well-established and safer treatments to restore ocular integrity and the patient’s vision.

The availability of donated corneas, thanks to the activities of Eye Banks, is a prerequisite for successful transplantation and the accessibility of corneal tissue. The preservation methods encompass the responsibilities of procuring, preserving, ensuring quality control, and preparing tissues for the operation theater. Furthermore, in recent years, imaging analysis of the cornea has improved allowing for quantitative as well as qualitative evaluation of several corneal parameters that represent biomarkers of disease progression. While some novelties will not find an application in the clinical practice, others will be successful and will become fundamental for patient management.

This Special Issue seeks to outline studies targeting the latest developments in surgery for various corneal diseases.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Clinical Medicine is an international peer-reviewed open access semimonthly journal published by MDPI.

Background: The aim of this study was to evaluate the intraoperative complications and visual outcomes of manual deep anterior lamellar keratoplasty (mDALK) in patients who underwent previous radial keratotomy (RK) for myopia. Methods: The notes of patients who underwent mDALK after RK at three different hospitals—San Giovanni Addolorata Hospital (Rome, Italy), Mount Saint Joseph Hospital (Vancouver, Canada), and Tor Vergata University Hospital (Rome, Italy)—were retrospectively reviewed. We analyzed the manual dissection success rate and conversion to penetrating keratoplasty (PK), the residual recipient stromal thickness, the postoperative corrected distance visual acuity (CDVA), postoperative refraction, and topographic astigmatism. Results: Thirteen eyes of eleven patients were included in the analysis (male 7/11, 63.6%). Preoperatively, mean topographic astigmatism was 5.4 ± 3.5 D (range 1.6–14.8 D), and mean CDVA was 0.47 ± 0.2 logMAR (range 0.3–1.0 logMAR) [Snellen equivalent 20/50]. Manual dissection was performed in all cases. None of the examined eyes were converted to PK. An improvement in both topographic astigmatism (2.8 ± 0.9 D, p = 0.0135) and CDVA (0.23 ± 0.2 LogMAR, p = 0.0122) was recorded at 12-month follow-up. Conclusions: mDALK is a safe and effective surgical technique when applied to eyes previously treated with RK, with an observed improvement in CDVA and topographic astigmatism. Full article
