AIM: To evaluate the results and complications of LASIK surgery in Yazd, Iran.METHODS: In this descriptive study, cases were selected randomly and data from files of 230 operated eyes were filled in a questionnaire with special format. Data of patients who had been operated upon between March 2003 and March 2004 were gathered and evaluated by SPSS software program, in particular, Chi-square and Fisher statistical tests. Patients were followed up for 3 months. Residual refractive error in the range of±0.5 was considered as complete correction and more than±0.5 considered as relative correction.RESULTS: From the total of 230 eyes, 122 eyes were of women and 108 eyes belonged to men. 24 cases (10.4%)were myopic; 188 cases (81.8%) were myopic-astigmatism; 5 cases (2.2%) were hyperopic and 13 cases (5.6%) were hyperopic-astigmatism 204 eyes were in the age group of younger than 40 years and 26 eyes were in the age group of older than 40 years. Based on visual acuity recovering condition, 225 eyes (97.8%) were treated completely and 5 eyes (2.2%) were relatively corrected. Patients were followed up for 3 months after surgery. The rate for complete correction of refractive errors in myopia was 96.0%, myopic astigmatism 88.0%, hyperopia 60.0% and hyperopic astigmatism 62.0%. At 3 months after operation, 224 cases (97.4%) did not have any complications and the others had minor side effects.CONCLUSION: LASIK operation is a safe and effective procedure for correcting refractive errors with limited complications. Results are comparable with similar studies.

· AIM: This study was conducted to compare the outcomes of amniotic membrane transplantation (AMT) with conjunctival autograft transplantation (CAT) in primary and recurrent pterygium. The main outcome measurement was the recurrence rate after surgery.· METHODS: This study was designed as a prospective study on consecutive cases of pterygium from April 2004 to Feb2006. The cases were randomly divided into two groups of AMT (26 cases) and CAT (24 cases). All subjects were operated with an extensive excision of the fibro vascular tissues with AMT or CAT approach. Patients were followed for recurrence and complications for 24 months. The surgical procedures were performed by a single surgeon.The associations between demographic variables, surgical techniques (AMT, CAT), recurrences and postoperative complications were analyzed.· RESULTS: The patients' male to female ratio was 4:1. Involvement of right to left eye ratio was 3:2. Pterygium in70% of cases was primary and in 30% was recurrent. The most common clinical signs were red eye and reduced visual acuity while the most common complications were recurrence and corneal scar. In the first month of follow up, the recurrence rates in AMT and CAT approaches were 3.8% vs 8.3%respectively and these rates increased to 46.2% vs 25% respectively after 24 months of follow up.· CONCLUSION: The success rate of 2 years follow up was better in CAT technique. The AMT technique for pterygium surgery has an unacceptably high recurrence rate.
