Rejuvenation of Visual Age After Laser Anterior Ciliary Excision to Restore Dynamic Range of Vision
Narrative Responses:
Purpose
To evaluate the potential impact of rejuvenating visual functional age by restoring dynamic accommodation in presbyopic population utilizing the Laser Anterior Ciliary Excision (LaserACE) procedure.
Methods
LaserACE provides good DCVA, DCIVA, and DCNVA in patients who have little to no crystalline lens opacity. The visual acuity results were measured in 42 eyes of 24 patient’s ages 44-57 treated with the LaserACE procedure for restoration of Natural Dynamic Accommodation by reduction of ocular rigidity. Results of objective measurements utilizing ray-tracing aberrometry, ETDRS customized VA cards set at 40cm and 60cm are reviewed. Results are plotted against Hofstetter’s & Duane’s curves. MAA's were then plotted over calendar age as an expression of Visual Age to demonstrate rejuvenation of accommodation.
Results
Preoperative and 6months postoperative accommodative amplitudes of each subject was plotted by calendar age. A correlation function found Post-op MAA = 0.4294 x Preop MAA + 2.2886. Data from this study were then plotted against objective amplitudes from previous studies of adults up to age 57. Mean age-related accommodative amplitudes (MAA) correlated with a postoperative rejuvenated visual age of an average of 5.33 years 6mos afterLaserACE correlating with a mean difference of 1.33D (p<0.05). All patients sustained improvement of MAA across all age groups.
Conclusion
When plotted with data from previous studies, the data collected from the LaserACE treated patients showed statistically significant restoration of accommodative power & ability to rejuvenate visual functional age by an average of 5 years and up to 10 years in some patients.
