The purpose of this study is to report the modification of sewing machine technique for iris dialysis repair (MSMT) and its usefulness in managing other conditions such as intraocular lens (IOL) subluxation, iris coloboma, Cionni ring for zonular dialysis, and for scleral-fixated IOL. MSMT was based on sewing machine principle using a prethreaded 26G/30G needle with prolene suture for minimally invasive iris dialysis repair in a closed chamber manner. So far, eight patients (trauma – 3, surgical complication – 5) underwent this procedure. This technique is further modified to extend its use for IOL relocation – 2, iris coloboma repair – 3, and Cionni ring fixation for zonular dialysis – 2, SFIOL – 5 patients. All 20 patients had good visual recovery and cosmetic outcome with minimal morbidity. To conclude, MSMT offers cost -effective, minimally invasive, easy to learn procedure with a potential to tackle several problems related with cataract surgery and iris defects, which even an average cataract surgeon can learn to perform when required. Further comparative studies with conventional techniques with large sample size are required to standardize this procedure.
