Immediate Postoperative Decentration of a Biologic Corneal Inlay Managed With Tomography‐Guided Repositioning: A Case Report

Clinical Case Reports, Volume 14, Issue 3, March 2026.
Immediate postoperative Pentacam corneal tomography revealing inferior‐temporal decentration of the biologic corneal inlay on the axial curvature map. ABSTRACT Biologic corneal inlays can rarely present with immediate postoperative decentration, which can be subtle and difficult to detect clinically. Real‐time tomography allows precise early diagnosis,

Corneal densitometry changes in keratoconus patients after intrastromal corneal ring segments implantation

Journal of the Egyptian Ophthalmological Society
Background Keratoconus (KC) is an ectatic corneal disorder characterized by progressive corneal thinning with myopic astigmatism. Intrastromal corneal ring segments (ICRS) have been broadly selected as a surgical intervention for KC correction to delay ...

Bioinspired Tissue Transparency: Achieving Sclera‐to‐Cornea Transplantation

Advanced Science, Volume 13, Issue 10, 18 February 2026.
A bioinspired decellularization‐compression‐locking tactic (DCLT) is developed to transform human sclerae into transparent corneal substitutes. These clear, robust, and pro‐regenerative substitutes are capable of repairing complex corneal injuries, including chemical burns, keratoconus, and penetrating wounds, demonstrating their clinical potential to ...

Long-term results of corneal wedge resections for the correction of high astigmatism [PDF]

, 1990
We retrospectively evaluated 41 corneal wedge resections, performed for the correction of high astigmatism in 40 patients who were spectacle and contact lens intolerant. Keratometric astigmatism decreased from an average of 11.7 diopters (range 5 to 22.5

A randomised controlled trial on cross‐linking protocols for the treatment of progressive keratoconus using isoosmolar and hypoosmolar riboflavin with the addition of sterile water in thin corneae

Acta Ophthalmologica, Volume 104, Issue 1, Page e63-e74, February 2026.
Abstract Purpose To present the outcomes of a randomised clinical trial for the treatment of progressive keratoconus using different kinds of riboflavin and the addition of sterile water in thin corneae. Methods A randomised study using epithelium‐off corneal cross‐linking (CXL) with continuous UVA irradiance 9 mW/cm2 for 10 min (total fluence 5.4 J ...

Preliminary validation of an optimized algorithm for intraocular lens power calculation in keratoconus

Indian Journal of Ophthalmology, 2017
Purpose: This study aimed to evaluate the theoretical influence on intraocular lens power (PIOL) calculation of the use of keratometric approach for corneal power (Pc) calculation in keratoconus and to develop and validate an algorithm preliminarily to ...

Management of Dry Eye Disease for Intraocular Lens Power Calculation in Cataract Surgery: A Systematic Review

Bioengineering
Cataracts are characterized by the crystalline lens of the eye becoming cloudy, and dry eye disease (DED) is a multifactorial disease in which the homeostasis of the tear film is lost.

Cataract Surgery in a Case of Bilateral Idiopathic Corneal Ascher Rings Associated With Anterior Segment Changes

Case Reports in Ophthalmological Medicine, Volume 2026, Issue 1, 2026.
Aim The aim of this study is to report an extremely rare case of corneal annular opacities, incidentally found in a patient referred for age related cataract surgery. Additional anterior segment particularities were detected in this patient. Methods Clinical and imaging methods were employed for a rigorous ophthalmological examination; a full systemic ...
