Resident experience with toric and multifocal intraocular lenses in a public county hospital system

To study the outcomes of toric and multifocal intraocular lens (IOL) implantation performed by resident surgeons.

Parkland Health and Hospital System, Dallas, Texas, USA.

Case series.

Patients seen between July 2008 and May 2011 and meeting inclusion criteria (including >1.0 diopter [D] of astigmatism in toric group and <0.75 D astigmatism in multifocal group) were offered implantation of the study IOLs. Major outcomes were uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA) and, for the multifocal IOL, near visual acuity. Residents were surveyed about their knowledge regarding these IOLs.

Seventy-nine eyes of 60 patients received an Alcon Acrysof toric IOL. Eighteen eyes of 10 patients received an Alcon Acrysof Restor IOL. In the toric group, 57% of eyes achieved a postoperative UDVA of 20/25 or better and 90% achieved 20/40 or better. The CDVA was 20/25 or better in 92% of eyes. The mean refractive cylinder was 1.69 D preoperatively and 0.38 D postoperatively. In the multifocal group, 78% of patients achieved a UDVA of 20/25 or better and 94% achieved 20/40 or better. All patients had a CDVA of 20/25 or better. Near vision was Jaeger 3 or better in 94%. The survey showed that residents have a strong comfort level with preoperative and surgical techniques for premium IOLs after their experience in the residency setting.

Residents in public county hospitals can be taught to use premium IOLs with good success rates, comparable to those in other published studies.
