Abstract
Purpose
To describe surgical technique and report short-term visual outcomes after suture-fixation of a single-piece eyelet-toric (SET) intraocular lens (IOL) for treatment of concurrent aphakia and astigmatism.
Design
Retrospective, noncomparative, and non-consecutive case series.
Methods
This was a case series of eleven eyes who underwent successful SET. 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.
