Researcher Eva Mönestam, MD, PhD, found effective, long-term visual rehabilitation 15 years after cataract surgery in a longitudinal study involving 190 patients.
Fifteen years after surgery, the median corrected distance visual acuity in the operated eye deteriorated from 20/20 postoperatively to 20/25.
Sixty percent of patients had worsening of corrected distance visual acuity (CDVA) of less than 0.1 logMAR units compared to postoperatively. A total of 54% had no deterioration in subjective visual function, and 79% had 10 points of decline or less, according to Mönestam.
Furthermore, women had a significantly more pronounced decline in CDVA over 15 years. However, after adjusting for age, the association was no longer significant.
Compared to 10 years after surgery, Mönestam found no statistically significant increase in the percentage of patients with worse visual acuity 15 years after surgery compared with preoperatively.
She concluded that most patients had good to excellent subjective visual function and retained visual acuity in the surgical eye 15 years after cataract surgery with modest rates of Nd:YAG capsulotomy. – by Abigail Sutton
