Piggyback Scleral Contact Lens to Enhance Cosmesis and Comfort in Uniocular Stevens-Johnson Syndrome.

Stevens-Johnson syndrome often results in a significant reduction in vision, dryness, and photophobia based on severity. Scleral lenses are well-considered visual interventions that enhance vision and comfort, resulting in an increased quality of life for patients. This case report describes the enhancement of comfort, cosmesis, and reduction of photophobia using a piggyback system (scleral contact lenses over a prosthetic contact lens), whereas the other modalities were unsatisfactory.

PROSE for irregular corneas at a tertiary eye care center.

Objective: The aim of this study was to report and discuss the clinical experience with PROSE (Prosthetic Replacement of Ocular Surface Ecosystem) practice at a tertiary eye care hospital.

Methods: Retrospective data of patients who were prescribed PROSE during April 2011 to March 2012 in a tertiary eye care center in south India were analyzed. Data collected include patient demographics, indications of scleral lens fitting, previous correction modality, PROSE parameters, best-corrected visual acuity (BCVA) with spectacles, and BCVA with PROSE at initial assessment and few hours of wear.

Tear fluid small molecular antioxidants profiling shows lowered glutathione in keratoconus.

Keratoconus (KC) is a non-inflammatory disease of the cornea involving structural changes. Oxidative stress is reported to be parts of its pathology, yet the tear antioxidant status contributed by smaller molecule antioxidants can be indicative of the disease. Therefore this study is an attempt to present the status of small molecule antioxidants in KC condition as well as the influence of contact lens wear (CLW) in KC as evaluated in the tear specimen.

Tear ascorbic acid levels and the total antioxidant status in contact lens wearers: a pilot study.

Aims: The tear ascorbate owing to its high concentration, functions as an effective antioxidant against the oxidative damage of cornea. Contact lens wearers (CLW) are prone to oxidative stress due to the lens-induced hypoxic conditions. A pilot study was done to compare the tear ascorbic acid level and the total antioxidant capacity give as in normal and CLW.
