TRIAL DESCRIPTION
Public title Lasik-induced corneal changes after correction of hyperopia with and without application of Mitomycin C
Official scientific title Lasik-induced corneal changes after correction of hyperopia with and without application of Mitomycin C
Brief summary describing the background and objectives of the trial Purpose: To assess the role of intraoperative mitomycin-C (MMC) application during hyperopic LASIK correction (+1.00 D to +6.00 D) by examining topographic corneal changes and incidence of regression over a one-year follow-up period. Methods: This comparative randomized control study included 136 eyes of 68 hyperopic patients divided into two groups; Group A included 68 eyes of 34 patients that had LASIK with the application of 0.02% MMC for 10 seconds on the stromal bed after excimer laser treatment, and group B included 68 eyes of 34 patients that had LASIK without MMC application. Uncorrected distance visual acuity (UDVA), refraction, keratometry and topography were recorded at 1st week and 1st, 3rd, 6th, and 12th months postoperation. Predictability and treatment efficacy were also recorded at the end of the follow-up period.

STUDY DESIGN
Intervention assignment Allocation to intervention If randomised, describe how the allocation sequence was generated Describe how the allocation sequence/code was concealed from the person allocating the participants to the intervention arms Masking If masking / blinding was used
Parallel: different groups receive different interventions at same time during study Randomised Simple randomization using a randomization table created by a computer software program Allocation was determined by the holder of the sequence who is situated off site Open-label(Masking Not Used)
INTERVENTIONS

Yes Better predictability was noted in group A than in group B at the 6 month and 12 month follow-up visits, with a mean cycloplegic refraction SE of +0.5 ± 0.31 D in group A and +0.67 ± 0.39 D in group B at the 6 month visit, and +0.63 ± 0.37 D in group A and +0.89 ± 0.48 D in group B at the 12 month visit. The efficacy of the treatment at the end of the follow up period was better in group A than in group B. Group A showed fewer topographic corneal changes than group B. 17/01/2019 17/01/2019
