Relevance. Lower lid retraction is a frequent undesirable result following inferior rectus recession operations. Especially in relatively larger amounts of recession, a special and close relationship between lower lid retractors and muscular fascia makes the complication more severe. Purpose of the study. To introduce two methods that allow wide inferior rectus recession without causing lower eyelid retraction and to evaluate the long-term results. Material and methods. There were 25 cases and 18 control group cases in first operation technique named ‘ninety percent of posterior fibers recession of inferior rectus’ which can be perform for any vertical deviation without muscle fibrosis; and 8 cases were in second operation technique which named ‘muscle elongation with both organic tissue and non-absorbable suture’. Results and conclusion. In both technique patients’ deviation corrected and all ocular movement was free. Both operation techniques, which introduces by us, does not affected lower lid retractor and operations has both effective results and no lid problem.
