Abstract

PURPOSE:

To assess astigmatic reduction and rotational stability of Rayner T-flex toric intraocular lenses (IOL) (573T and 623T; Rayner Intraocular Lenses Ltd) in a series of cataract surgery patients with corneal astigmatism >1.50 diopters (D).

METHODS:

This prospective, observational study included 27 eyes from 22 consecutive patients with pre-operative regular corneal astigmatism ≥1.50 D in which Rayner T-flex toric IOL implantation was performed after phacoemulsification. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), residual refractive sphere, residual keratometric and refractive cylinder, and deviation from attempted toric IOL axis were measured.

RESULTS:

Mean UDVA 3 months after surgery was 0.1042±0.1290 with 20/40 or better in 96% of eyes and 20/25 or better in 52% of eyes. Mean refractive postoperative sphere was 0.25±0.37 D and mean refractive postoperative cylinder was 0.52±0.63 D. Vector analysis of attempted versus achieved visual correction showed that 100% of eyes were within ±1.00 D and 87% of eyes were within ±0.50 D. Mean change in keratometric astigmatism was 0.54±1.33 for J(0) and -0.24±1.17 for J(45) (P>.05). Twenty-five (92.6%) eyes had IOL rotation <10°.

CONCLUSIONS:

Rayner T-flex toric IOL implantation is an effective and reliable option to correct preexisting astigmatism in cataract surgery.
