ReSTOR lens shows strong results in 12-month clinical results

Lisbon, Portugal - The AcrySof ReSTOR lens (SA60D3, Alcon Laboratories) has shown promise in restoring pseudoaccommodation for patients with presbyopia and hyperopia, according to Tobias Neuhann, MD, of Munich, Germany.

Dr. Neuhann presented 12-month clinical and visual acuity results for distance and near vision for the single-piece acrylic lens during an ESCRS free paper session on refractive surgery outcomes for presbyopia on Sunday.

The monocular and binocular distance and near visual acuity, as well as the dioptric range, of the implanted lenses in 76 eyes of 40 patients were followed in a prospective randomized trial. All patients also participated in a lifestyle and function questionnaire to judge their satisfaction as a result of the surgery.

Among the 40 patients, there were 11 males and 29 females. The mean age of the males was 63.4 and mean age for the females was 62.5. The age range was 19 to 86 years. Refractive lens exchange for presbyopia was the reason for the surgery for 54.5% of the males, and 41.4% of the females. Phacoemulsification was performed on all the patients by one physician, with no complications. Four patients had a lens exchange because of a refractive miscalculation.

In reporting his results of the ReSTOR lens, Dr. Neuhann said the mean for the uncorrected visual acuity was 20/25, with a range of 20/40 to 20/15 for all patients. Mean for uncorrected near vision acuity was J2 or better, with a range of J3 to J1+. The best-corrected visual acuity was 20/20 or better for all patients.

When distance correction was plano, intermediate vision at 60 cm for all patients averaged J5 or better 4 weeks after surgery. However, distance vision improved to J4 or better after 12 months. With distance correction of +0.75 D, intermediate vision also improved significantly.

Dr. Neuhann concluded that the apodized pseudoaccommodative IOL provides good unaided distance and near vision with few early postoperative complaints about the lack of the same good intermediate results. However, he added that problems with intermediate vision for most patients have been resolved at 12 months.

“[The ReSTOR] offers real good vision, and has very good near vision results,” added Dr. Neuhann. “It’s fair for intermediate vision. [Overall], it’s excellent for presbyopia and hyperopia patients.”
