Abstract Details

Purpose:

To evaluate binocular reading performance in patients previously implanted with the Raindrop® Near Vision Inlay (ReVision Optics, Inc., Lake Forest, CA, USA) in one or both eyes.

Setting:

Laser Ocular Hidalgo, Monterrey, Mexico

Methods:

Patients previously implanted with Raindrop corneal inlays were consecutively enrolled into this study. All patients were at least 6 months postoperative following uncomplicated inlay implantation in either unilaterally (R, n=19) or bilaterally (RR, n=12). Binocular visual acuities and reading performance was evaluated prospectively. Reading speed was measured photopically under distance correction at near (40 cm) with a Spanish reading chart (similar to MNRead). Results were digitally voice recorded and analyzed for maximum reading speed (MRS; wpm), critical print size (CPS; logMAR), and reading acuity (RA; logMAR).

Results:

Average postops were similar between both groups (RR:32M vs R:33M). Mean MRSE in the inlay eye were statistically different (RR:+0.22 D vs R:-0.59 D, p=0.01). Binocular UCVAs were slightly better in the bilateral group for near (RR:0.14 vs R:0.24) and slightly better in the unilateral group for distance (RR:0.12 vs R:0.07). Both groups performed equally well with MRS (RR:210 vs R:194), CPS (RR:0.37 vs R:0.42), and RA (RR:0.12 vs R:0.19). At 0.3 logMAR (20/40), the bilateral group read faster than the unilateral group, but this difference was not statistically significant (RR:138 vs R:93, P=0.11).

Conclusions:

Patients implanted with Raindrop Inlay for the correction of presbyopia in one or both eyes performed equally well reading at near. Both groups showed efficient reading speeds at standard print size of 20/40.
