Purpose: To evaluate the effect of lens aspiration and anterior vitrectomy in the development of retinal detachment in eyes with non-traumatic ectopia lentis. Methods: This retrospective study evaluated patients with non-traumatic ectopia lentis Traumatic cases and patients with Stickler syndrome were excluded. The eyes were divided into two groups: eyes that had undergone lens aspiration and anterior vitrectomy (surgical group) and, eyes that had no surgical intervention (non-surgical group). The risk of developing retinal detachment in both groups was evaluated. P<0.05 was considered statistically significant. Result: The study sample was comprised of 115 eyes of 63 patients. There were 36 (57.1%) and 27 (42.9%) females. The median age of patients was 14 years (25% quartile, 8; minimum, 2 year and maximum, 55 years). There were 74 eyes in the non-surgical group. There were 41 eyes in the surgical group that had undergone Lensectomy (31 limbal approach and 10 pars plana) with intraocular lens implantation in 22 (19%) eyes. The incidence of retinal detachment (n=25) was 21.7% (95% confidence interval: 17.7 to 25.4). Seventeen (23%) eyes in the non-surgical group developed retinal detachment and 8 (19.5%) eyes in the surgical group developed retinal detachment (P = 0.7). Conclusion: There was no difference in the incidence of retinal detachment between eyes with ectopia lentis that undergone lensectomy with or without IOL implantation compared to eyes that had not undergone any surgery. However, larger studies are required to evaluate the effect of lens aspiration on the development of retinal detachment in patients with ectopia lentis.
