Abstract Background: To compare conjunctival autograft and combined amniotic membrane mini-simple limbal epithelial transplant after primary pterygium excision Methods: A prospective randomized interventional study was conducted on 264 eyes with Primary Pterygium.The patients were divided into Group I (conjunctival autograft) and Group II (mini-simple limbal epithelial transplant). 133 eyes in Group I underwent pterygium excision with a conjunctival autograft using fibrin glue. 131 eyes in Group II underwent mini Simple Limbal Epithelial Transplant with amniotic membrane using fibrin glue. Post-operatively, the patients were reviewed on day 1,3,7,14 & 30 and then at three,six and nine months. Primary outcome measure was the recurrence rate whereas the secondary outcome measures were the intraoperative time and other complications.Recurrence rate was calculated using Fisher’s exact test. Variables like age , preoperative BCVA , operative time and the dimensions of graft were compared using unpaired t test . Other baseline characteristics like gender, Laterality, grades of pterygium(I-III),Occupation and indication of surgery were expressed between the two groups using Pearson’s Chi-Square test. Results: Two hundred and thirty three eyes(118 in group I and 115 in group II) could complete nine months follow-up period. Recurrence was seen in 2(1.6%) cases in group I whereas 3 cases (2.6%) had recurrence in group II(p=0.681).Operative time for group (II) (20.33±1.28 min) was significantly higher (p<0.001) than group I (12.01±1.26). Graft displacement occurred in one case in group II (p=0.999). Conclusions: Despite a longer time,(p<0.001) mini-SLET seems to be a viable and equally effective alternative to CAG in the management of primary pterygium ,especially in cases where conjunctiva needs to be spared.Ethical Clearance Certificate Number : 29/MH/2015 dated 11 Aug 2015

Background: Pterygium causes visual problems due to induced corneal astigmatism or direct encroachment onto the visual axis. The present study was conducted to compare preoperative and postoperative changes in corneal astigmatism after pterygium excision by different techniques. Subjects and Methods: The present study was conducted from May 2018 to August 20018 on 69 patients of age range 20-55 years of primary Pterygium. Patients were divided into three groups of 23 each. Group I was treated with bare sclera (BS) technique, Group II with conjunctival autograft (CAG) technique and Group III with amniotic membrane graft (AMG) technique. All the patients were preoperatively assessed for visual acuity, anterior and posterior segments, autorefraction, and autokeratometry. After surgery, the patients were recalled on day 5, 1 month, and 3 months for the analysis. Results: Uncorrected visual acuity (UCVA) preoperatively was 0.57, on the 5th day was 0.45 after 1 month was and after 3 months was 35. The mean preoperative astigmatism value in group I was 3.45, in group II was 3.52 and in group III was 3.49. Postoperative astigmatism value in group I was 1.60, in group II was 0.92 and in group III was 0.81. The difference was significant (P< 0.05). Conclusion: Authors found that amniotic membrane graft and a conjunctival autograft is better surgical techniques than bare sclera in reducing astigmatism.

Purpose: To compare the recurrence rate of primary pterygium surgery after the adjuvant use of Beta radiation, Mitomycin C, and conjunctival autograft. Methods: 180 eyes of 180 patients were included in the study. All cases had primary pterygium excision following the use of adjuvant therapy of Beta radiation or Mitomycin C (0.02% for 5 minutes) or conjunctival autograft. The study was conducted at Fayoum University Hospital, Fayoum, Egypt, and Misr University Hospital. The patients were randomly divided into three groups, with each group comprising 60 patients. Group (A) included patients treated with Beta radiation following Pterygium excision, group (B) patients had primary pterygium excision with the application of 0.02% Mitomycin C for 5 minutes, and group (C) patients had conjunctival autograft to cover the bare area after pterygium excision. Patients were followed up for three years postoperatively. Results: group A had the highest recurrence rate (33.3%) followed by group B (13.3%), and finally group C presented a recurrence rate of 6.7%. Group B showed the highest rate of intra-ocular postoperative complications, while no intra-ocular complications were recorded in group C. Common complications in groups A and B were scleral melting, keratitis, and Dellen formation. Conclusion: Using conjunctival autograft after primary pterygium excision gives the best results regarding the rate of recurrence and postoperative complications. Meanwhile, B-radiation or Mitomycin C did not prove to be as good.
