Abstract Details


To evaluate improvement in near vision with scleral implant procedure and PMMA implants in emmetropic presbyopes.


fourteen principal investigator sites throughout USA


This prospective study measured DCNVA under standardized illumination pre-op, 3, 12, and 24 months after successful scleral implant procedure on 629 eyes of 328 patients. Inclusion criteria required 20/20 DCVA, manifest refraction SE between –0.50 to +0.75D, with up to 1.00D astigmatism, and 20/50 or worse DCNVA.


Pre-op mean DCNVA was 20/73. Post operatively 60%, 79%, and 96% of the eyes read 20/40 or better monocular DCNVA at 3 (n=434), 12 (n=214), and 24 (n=95) months respectively. Binocular DCNVA of 20/40 or better was achieved with 84%, 85% and 96% of the patients at these time intervals


DCNVA improves over time with scleral implant procedure. Patients had better DCNVA when both eyes underwent scleral implant procedure and were measured together.
