Isolated keratinising corneal ocular surface squamous neoplasia with multifocal recurrence.

Corneal ocular surface squamous neoplasia usually begins at the limbus and presents as an avascular translucent sheet over the corneal surface. This case report describes a 67-year-old man with an unusual isolated, keratinous nodular corneal lesion. Slit-lamp examination showed an elevated, avascular, whitish plaque-like lesion at the central cornea surrounded by a normal corneal epithelium, with reduced visual acuity of 20/200 in the right eye.

Descemet Membrane Endothelial Keratoplasty for Failed Penetrating Keratoplasty: Visual Outcomes and Graft Survival.

Purpose: To evaluate outcomes and graft survival of Descemet membrane endothelial keratoplasty (DMEK) for failed penetrating keratoplasty (PK).

Methods: Ninety-three DMEK procedures performed in 84 eyes of 77 patients with failed PK were retrospectively reviewed. The main outcomes were corrected distance visual acuity and graft survival assessed with Kaplan-Meier survival analysis and proportional hazards modeling taking follow-up into consideration.

Vernal keratoconjunctivitis: culmination of management using immunosuppression, surgical and prosthetic therapy over quarter century.

A 22-year-old male patient presented in 1988 with active vernal keratoconjunctivitis. He was treated with topical mast cell stabilisers and corticosteroids. Chronic inflammation despite topical treatment necessitated oral immunosuppressants.

Outcomes of topography-guided versus wavefront-optimized laser in situ keratomileusis for myopia in virgin eyes.

Purpose: To compare the outcomes of topography-guided and wavefront-optimized treatment in patients having laser in situ keratomileusis (LASIK) for myopia.

Setting: Advanced Eye Centre, Post Graduate Institute of Medical Education and Research, Chandigarh, India.

Design: Prospective contralateral-eye case study.
