SAN FRANCISCO — Complaints of glare or reduced night vision were virtually non-existent in a study of patients implanted with the SofPort AO silicone aspheric lens, P. Dee G. Stephenson, MD, said.

Dr. Stephenson compared the Bausch & Lomb SofPort AO, SofPort SE and Tecnis (Advanced Medical Optics) lenses. Dr. Stephenson said patients implanted with the two non-aspheric lenses had night glare problems and required Nd:YAG laser within 9 months after initial implantation.

Since September 2004, Dr. Stephenson has implanted 525 SofPort AO lenses. By 1 year postop, she said 150 of her patients were 20/40 or better without correction and 85% had 20/20 best corrected visual acuity. Patients also reported improved night vision, which was a major consideration for them, she added here at the American Society of Cataract and Refractive Surgery meeting.

“In my practice, this is the number one complaint — about a decrease at night time driving,” she said.

In addition, if decentered, the SofPort AO does not induce higher order aberrations, Dr. Stephenson said. If tilted, it induces less higher order aberrations than other IOLs, she added. The effective lens power is unaffected by pupil size, she stated.
