Eligible eyes had loss of capsular support or aphakia with a minimum of symmetric corneal astigmatism 1.75 diopters (D). Outcome measures included uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), magnitude of residual refractive cylinder, and complications resulting from the SET procedure.Results: Preoperative UDVA and CDVA in logMAR scale were 1.46 and 0.45, respectively. Mean preoperative keratometric and refractive cylinder were 3.67 D and 2.52D, respectively. Postoperative UDVA and CDVA were 0.51 and 0.27, respectively, three months after surgery (POM3). Residual refractive cylinder at POM3 was 0.93 D.Conclusion: SET technique reduced refractive cylinder and improved UDVA and CDVA. SET may be adapted by surgeons using a readily available IOL and familiar scleral-fixation maneuvers.Keywords: aphakia, toric, suture fixation, secondary lens, astigmatism |
