This year, ophthalmologists from around the world attended the American Society of Cataract and Refractive Surgery (ASCRS) Symposium in Boston (April 2010). One of Dr. Jonathan Davidorf’s presentations detailed the results of an ongoing prospective study designed to describe the visual function and level of spectacle independence of cataract surgery patients with ReSTOR or Crystalens lens implants. Of the current cohort, there are 98 eyes of 49 patients who underwent cataract surgery in both eyes and received either the ReSTOR D1 (+3D add) or Crystalens HD intraocular lens implant.
Patients were asked to rate their degree of spectacle independence following their procedure. Key activities for which ReSTOR patients reported rarely (if ever) wearing glasses were day driving (93%), night driving (89%), computer use (88%), and reading books (79%). Crystalens patients reported rarely (if ever) wearing glasses for day driving (79%), night driving (68%), computer use (83%), and reading books (83%).
Patients were also asked to rate their satisfaction with the results of their procedure on a scale of one (dissatisfied) to ten (extremely satisfied). The mean satisfaction scores were 8.7 (ReSTOR) and 7.6 (Crystalens).
The results document a high degree of spectacle independence in both groups. It is important for patients to understand that, while complete spectacle independence is the goal, reasonable expectations are for an extreme decreased dependency on spectacles.
