Efficacy and Refractive Outcomes of a Plate-Haptic Toric Monofocal IOL in Asian Eyes
To describe the efficacy, refractive outcomes and safety of the AT Torbi 709M toric (Carl Zeiss Meditec) intraocular lens in Asian eyes.
Prospective analysis of all eyes undergoing phacoemulsification surgery which had implantation of the AT Torbi 709M IOL for the correction of cataracts and refractive error. All surgeries were performed by 1 surgeon at the Singapore National Eye Centre and all patients were followed-up for at least 4 months post-operation. All patients underwent conventional phacoemulsification surgery followed by IOL implantation in the capsular bag. Preoperative visual acuity and refractive error were recorded. Postoperative unaided and aided visual acuity, refractive error and complications were recorded.
Seventy eyes are included in this study to date (number will be likely to be higher by the time of the conference). There were 52 Chinese, 27 Malay and 1 Indian eyes. 24 eyes (34.3%) achieved unaided distance visual acuity of 20/20 after 1 month postoperation. 65 eyes (92.9%) achieved best-corrected visual acuity of 20/40 or better after surgery. All eyes achieved a best-corrected vision of 20/40 or better. The mean postop spherical equivalent was +0.23 +/1 0.93 D. The mean preop cylinder was -1.65 +/- 0.16 D and the mean postop cylinder was -0.41 +/- 0.06 D.
The use of the AT Torbi toric monofocal IOL resulted in good postoperative unaided and aided distance visual acuity in Asian eyes.
