Abstract Details



Purpose:

To evaluate the feasibility of bilaterally implanting hydrogel corneal inlay (Raindrop Near Vision Inlay, ReVision Optics, Inc., Lake Forest, CA, USA) in low hyperopic presbyopes.

Setting:

Laser Ocular Hidalgo, Monterrey Mexico, CODET Vision Institute, Tijuana Mexico

Methods:

All inlays were implanted under a femtosecond flap (1/3 CCT) onto the stromal bed, centered on the light constricted pupil. Twenty-three hyperopic (+1.00 to +1.75 D Sph, -0.75 D of cyl or less), presbyopes were implanted with Raindrop in the non-dominant eye, followed for 3 to 6 months, and then implanted with a second inlay in the dominant eye. ETDRS visual acuity, task performances, visual symptoms and patient satisfaction were evaluated. The non-dominant and dominant eyes in the same subject responded similarly to the corneal inlay and therefore results are presented for binocular vision.

Results:

Uncorrected binocular visual acuity for near (UNVA) improved from (mean) preop 0.54 logMAR to -0.04 logMAR at 3 months, and remained stable over time (p > 0.05). Intermediate and Distance binocular VA followed similar patterns to near (3 month visit, 0.02 logMAR UIVA, and 0.01 logMAR UDVA), all were stable over the follow-up periods. Photopic and mesopic task performance improved postoperatively at all distances. Mild halos were seen at 3 months in 10% of patients, but disappeared at later visits. At 9 months, all patients were Satisfied or Very Satisfied with the procedure according to self-reported questionnaire.

Conclusions:

In low hyperopic presbyopes, bilateral implantation of the Raindrop Near Vision Inlay appears to be an effective alternative to correct presbyopia. It improves near and intermediate vision without compromising distance VA; task performance improves significantly at all distances for both good and dim lighting conditions.
