Progression and topographic subtypes of Terrien marginal degeneration

Acta Ophthalmologica, Volume 104, Issue 1, Page 33-43, February 2026.
Abstract Purpose To report long‐term outcomes and to search for immunological and genetic risk factors in Terrien marginal degeneration (TMD). Methods Retrospective, in part prospective, hospital‐based longitudinal follow‐up study of 32 eyes of 16 Finnish patients from 2012 to 2023. Median follow‐up was 7.3 years (range, 0.3–15.2).

Selective Laser Sintering 3D Printing of Drug‐Loaded Intravitreal Implants

Advanced Functional Materials, Volume 36, Issue 4, 12 January 2026.
Selective laser sintering enables the fabrication of biodegradable and biocompatible intravitreal implants with tunable microstructures for sustained drug delivery. By modulating laser scanning speed, the polymer matrix architecture is engineered to control the release kinetics of dexamethasone and riboflavin over several months. This approach offers a

Comparison of Surgically-induced Astigmatism using Topography and Keratometry in Patients undergoing Phacoemulsification and Small Incision Cataract Surgery: A Prospective Interventional Study [PDF]

Journal of Clinical and Diagnostic Research
Introduction: Topographic measurement of corneal astigmatism is the current standard of care because, in addition to measuring corneal astigmatism, it identifies irregular astigmatism, which may limit optimum surgical results.
