Purpose:
To evaluate the DCNVA improvement with SSP and PMMA implants (PresView Scleral Implants: PSI, Refocus Group, Dallas, TX) at 3, 12 and 24 months post-op in emmetropic presbyopes
Setting:
FDA monitored Investigational Device Exemption (IDE) sites in the United States in Beverly Hills, CA; Buffalo, NY; Nashville, TN, New York, NY; and San Antonio, TX
Methods:
A prospective study was performed which measured DCNVA monocularly and binocularly under standardized mesopic illumination pre-operatively and at 3, 12, and 24 months post-operative successful SSP with PSI on 95 eyes of 52 consecutive patients in the USA FDA monitored IDE study. Patient inclusion criteria required 20/20 distance corrected visual acuity (DCVA), manifest refraction spherical equivalent between +0.75D, with1.00D or less astigmatism, and 20/62 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 20/74 ranging from 20/62 to 20/160. Post operatively 54%, 78%, and 100% of the eyes read 20/40 or better monocular DCNVA at 3, 12, and 24 months respectively. Binocular DCNVA of 20/40 or better was achieved with 83%, 94% and 100% of the patients at the same time intervals
Conclusions:
The improvements in DCNVA with SSP improve over time. Patients had better DCNVA when both eyes underwent SSP and were measured together
