Long-term changes and effect of pterygium size on corneal topographic irregularity after recurrent pterygium surgery

The effect of pterygium surgery on contrast sensitivity and corneal topographic changes

PURPOSE To investigate the effect of pterygium surgery on corneal topography and contrast sensitivity. PATIENT AND METHODS The IRB approved this prospective, nonrandomized, self-controlled study. Computerized videokeratography (Orbscan II) was performed in 36 patients with primary pterygia, both before and 1 month after pterygium excision with limbal-conjunctival autografting. The topographic...

A Corneal Graft Operation for Recurrent Pterygium.

Effect of Pterygium Surgery on Tear Osmolarity

Purpose. To investigate changes of dry eye test results in patients who underwent pterygium surgery. Methods. Seventy-four patients who underwent primary pterygium surgery were enrolled in this study. At the baseline, 3-, 12-, and 18-month visits, measurements of tear osmolarity, BUT, and Schirmer test were performed. The patients were divided into 2 groups: Group 1, which consisted of patients...

Conjunctival Short-term Evolution after Pterygium Excision.

PURPOSE To analyze conjunctival cytological features 1 month after pterygium excision using limbo-conjunctival autograft (LCA) with and without intraoperative mitomycin C and to assess tissue short-term evolution in both situations. METHODS Fifty-nine primary nasal pterygia from 59 patients were excised with LCA. Twenty-nine were treated with intraoperative mitomycin C 0.02% (MMC+) and 30 wer...

Effects of Pterygium Excision on Corneal Curvatures

Objective: To determine the difference in mean corneal curvatures before and after pterygium excision, by using automated refraction and keratometry. Methodology: This quasi-experimental study was conducted at Eye Unit-I, Bahawal Victoria Hospital, Bahawalpur, from March 2010 to August 2010. Thirty patients with primary pterygium were analyzed before and after pterygium surgery for corneal curv...
