Abstract

Purpose

This study aims to evaluate the effectiveness of multifocal and toric multifocal intraocular lens implants in achieving spectacle independence when used in cataract surgery and clear lens extractions.

Methods

Case records were examined retrospectively for 218 eyes of 109 consecutive patients (38 male) who underwent lens extraction with multifocal intraocular lens implant by a single surgeon. If corneal astigmatism was present appropriate corrective procedures were undertaken: this included 38 eyes which received a toric multifocal lens. Data collected included: demographics, pre-operative corrected visual acuity (with habitual correction), post-operative unaided visual acuity for near and distance, degree of spectacle independence, and complications of surgery.

Results

Over 90% of patients reported spectacle independence for daily activities. Complication rates were low, with tolerable glare and haloes being the most common problem. Approximately half required laser capsulotomy for posterior capsule opacification.

Conclusion

In conclusion, multifocal intraocular lens implants can allow carefully selected patients to achieve spectacle independence. These results compare favourably with published data.
