Abstract:AIM: To evaluate Orbscan II corneal topography in hyperopic cases. METHODS: A retrospective, observational, consecutive, clinical case series in 295 eyes of hyperopic patients who undergo a LASIK evaluation. The information that was reviewed included age, sex of the patients and the Orbscan II corneal topographic maps. Refractive powers and the following test indices produced by Orbscan II were analyzed: keratometry, corneal diameter, pupil diameter and anterior chamber depth. · RESULTS: The total mean corneal thickness was 546.3±35.5μm. It was found; 547.3±38.4μm in 17-29 years old, 553.4±38.3μm in 30-44 years old and 546.2±29.3μm in older than 45 years old. The mean corneal thickness was found 551.5±35.9μm in female, and 542.6±34.7μm in male. The total mean depth of anterior chamber was 2.57±0.40mm and in 17-29 years old patients was 2.82±0.39mm. In 30- 44 years old patients was 2.49±0.39mm and in patients older than 45 years old was 2.37±0.40mm. The mean depth of anterior chamber was 2.53±0.40mm in female and 2.60±0.40mm in male. A reverse significant relation between corneal thickness and keratometry were found. Refractive error severity had a reverse correlation with depth of anterior chamber and a correlation with keratometry (P =0.061, r = 0.108).Corneal thickness had a reverse correlation with keratometry (P =0.005, r =0.160), and correlation with pupil diameter (P =0.013, r =0.144). · CONCLUSION: We provides a description and analysis of Orbscan II findings in hyperopic patients These show mean corneal thickness 546.3±35.5μm and anterior chamber depth 2.57±0.40mm in hyperopic patients.
