To survey patient satisfaction following Presbyopic Lens Exchange (PRELEXTM) in healthy, non-cataractous eyes implanted with the ReSTOR apodized diffractive lens.
Sixty presbyopic ametropes (115 eyes) who, upon examination, were considered poor candidates for corneal laser surgery and who were particularly motivated to correct both their near and distance vision were enrolled in the study. Mean preoperative spherical equivalence was +2.00 D. Major subjective outcome was evaluated with a detailed, 16 question, patient satisfaction questionnaire addressing the impact of PRELEX TM on patients’ daily activities. Patients were surveyed between their 3 and 6 month, as well as, their 6 and 12 month post-operative examinations.
Overall satisfaction (10 point scale) for uncorrected near and distance vision was 75% and 68% respectively between 3 and 6 months and increased to 86% and 83% between 6 at 12 months. Perception of severe halos decreased from 32.14% between 3 and 6 months to 13.33% between 6 and 12 months. Spectacle independence for distance, near, intermediate activities was 100%, 90% and 83% respectively between 6 and 12 months. Only 7% of patients would not repeat the procedure could they have gone back in time. Secondary corrective procedures included LASIK/PRK enhancement of residual refractive error (23 eyes), and exchange to monofocal lenses (2 eyes), in 19.8% and 1.7% of eyes. All secondary procedures were performed after at least 3 months of bilateral PRELEXTM.
Patient satisfaction reveals that Prelex is an effective procedure for ametropic patients who are poor candidates for corneal laser surgery and who are willing to correct their near, intermediate and distance vision. Although halos/glare are present early after PRELEXTM with ReSTOR, they seem to decrease in frequency and intensity after longer follow-up.
