Purpose:
To evaluate the improvement in DCNVA with SSP and PMMA implants (PresView Scleral Implants: PSI Refocus Group, Dallas, TX) at 6, 12 and 18 months post-op in emmetropic presbyopes.
Setting:
FDA monitored Investigational Device Exemption (IDE) site in the United States in Buffalo, NY with Dr. Mike Endl.
Methods:
A prospective study was performed which measured DCNVA monocularly and binocularly under standardized mesopic illumination preoperatively and at 6, 12, and 18 months post-operative successful SSP with PSI on 58 eyes of 29 consecutive patients in the USA FDA monitored IDE study at Buffalo, NY. Patient inclusion criteria required 20/20 distance corrected visual acuity (DCVA), manifest refraction spherical equivalent between +0.75D, with 1.00D or less astigmatism, and 20/50 or worse DCNVA. Patients were encouraged to aggressively use artificial tears and to increase illumination in favor of using glasses when reading in the early post-op time frame. Results at these time intervals were then compared. RESULTS Pre-op mean DCNVA was 20/71 ranging from 20/50 to 20/100. Post operatively 79%, 83%, and 94% of the eyes read 20/40 or better monocular DCNVA at 6, 12 and 18 months respectively. Binocular DCNVA of 20/40 or better was achieved with 94%, 100% and 100% of the patients at the same time intervals.
Conclusions:
Results show DCNVA improves with time after surgery, suggesting a possible need for rehabilitation of the accommodative system. Further, the greater improvement in DCNVA seen on an OU versus primary eye basis suggests involvement of the triad of accommodation.
