Abstract Details

Purpose:

To evaluate the efficacy and safety of the Rayner toric intra-ocular lens

Setting:

This study is a prospective, single-centre, 2-armed, 6-month clinical trial

Methods:

150 subjects requiring corneal astigmatic correction of more than 0.75 dioptre (D) are recruited. There are two phases of the study. In phase I, 50 subjects requiring cylinder correction of 1.51 – 4.0 D would be implanted with Rayner Toric IOL (model 623T). In phase II, 100 subjects requiring cylinder correction of 0.75-1.50D would be randomized to receive either Rayner toric (623T) or Rayner one-piece monofocal (970C flex or 920H Superflex) intra-ocular lens. The primary outcomes are mean percent reduction in cylinder and mean refractive cylinder at 24 weeks. The secondary outcomes are visual acuity, manifest refraction and IOL position.

Results:

Phase I of our study has been completed. The mean age of patients at the time of operation was 71.8 ± 15.8 years old. Mean preoperative unaided visual acuity was 0.74 LogMAR. Mean preoperative refractive cylinder was -3.52 D and mean preoperative keratometric cylinder was -2.66 D. In week 12, mean percent reduction in cylinder was 70.9 percent (p<0.05). The mean refractive cylinder was -1.00 D. There was no documented intraoperative complication. Secondary operation for adjustment of intraocular lens, lens exchange or lens explantation were not needed.

Conclusions:

The Rayner toric IOL was found to be a safe option in reducing regular corneal astigmatism of patients with cataract and corneal astigmatism.
