ABSTRACT
PURPOSE:
The objective was to evaluate the effect of co-implantation of a preloaded capsular tension ring (CTR) and aberration-free monofocal intraocular lens (IOL) on clinical outcomes and visual quality after cataract surgery. MATERIALS ANDMETHODS:
Patients who underwent cataract surgery were randomized into two groups that were implanted with a CTR and IOL (group 1, 26 eyes) or an IOL only (group 2, 26 eyes). At 1 and 3 months after surgery, visual acuity, refractive errors, refractive prediction errors, ocular aberrations, and modulation transfer function (MTF) were analyzed. At 3 months postoperatively, anterior chamber depth (ACD) and contrast sensitivity were evaluated.RESULTS:
Group 1 showed greater hyperopic shift, which caused the refractive prediction error at 3 months after surgery to be significantly different between the two groups (p=0.049). Differences in ACD between the preoperative and postoperative periods tended to be greater in group 1 than in group 2. At 3 months postoperatively, internal MTF values at 20, 25, and 30 cycles per degree were significantly better in group 1 than in group 2 (p=0.034, 0.017, and 0.017, respectively). Contrast sensitivity showed comparable results at almost all spatial frequencies between the groups.CONCLUSION:
Regarding visual acuity and quality, both groups showed comparable results. Co-implantation of a CTR and aberration-free monofocal IOL was associated with hyperopic refractive outcomes. Surgeons should consider the position of the IOL when planning co-implantation of a CTR and IOL.
