To provide patients with bilateral distance vision and monocular near vision in the non-dominant eye of hyperopic presbyopes via a combined treatment using LASIK and a hydrogel corneal inlay.
25 hyperopic, presbyopic subjects were implanted with 2.0 mm diameter hydrogel intracorneal inlays concurrently with a LASIK procedure to correct hyperopia (mean preop sphere 1.9 D [+1 to +3 D]). The Optec® 6500 Vision Tester was used to record visual acuities. Ability to perform everyday tasks (5 tasks for each of three distance ranges) without additional visual aid was ascertained using a questionnaire. The study was under an IRB-approved protocol.
In the implanted eye, near uncorrected visual acuity (UCVA) improved in 100% of eyes at 1 month, by an average of 7 lines. More than 80% of implanted eyes achieved J1 (20/25) or better near UCVA compared to 0% preoperatively. This was maintained at 6 months (n = 11) at which point all patients could read the J1 line binocularly. Intermediate UCVA improved in 100% of implanted eyes at 1 month, by an average of 5 lines to an average of 20/25. Only one patient lost distance UCVA in the implanted eye at 1 month (by one line), and improvement averaged 2 lines. Binocular UCVA was 20/20 or better for 100% of patients at both 1 month and 6 months post-op, improving from an average of 20/40 pre-op. At one month, 13 of the 15 visual tasks could be performed by all patients with one patient not being able to read distant street signs and two not being able to read medicine labels. By 6 months only one patient reported inability to perform one task throughout all distance ranges.
Significant improvement was found in near, intermediate and distance UCVA, with a corresponding increase in ability to perform everyday tasks without additional visual aid. The ReVision Optics intracorneal inlay is an effective tool to improve vision at all distances in hyperopic presbyopes with concurrent LASIK correction.
