Abstract Details


To evaluate the accuracy of inlay centration through wavefront maps and its effect on uncorrected visual acuity when implanting a thin presbyopia-correcting hydrogel inlay (Raindrop Near Vision Inlay).

Raindrop Near Vision Inlay is a small hydrogel inlay implanted under a femtosecond laser corneal flap, centered on the light constricted pupil. We analyzed retrospectively 125 subjects that were implanted with the inlay (targeting the center of the pupil). Wavefront aberrometry (iTrace, Tracey technologies) was used to determine inlay position within the pupil [target in the X (temporal/nasal) and Y (inferior/superior) directions relative to the pupil center]; Uncorrected visual acuity (distance, intermediate, and near) was assessed using standardized ETDRS charts to evaluate the effects of inlay centration.


Uncorrected visual acuity remained stable at very high levels (0.1 logMAR for distance, intermediate and near) in subjects with up to 0.9 mm of inlay decentration (98% of all inlays) measured at 1 month with iTrace wavefront scans. In eyes with inlay decentration between 0.9 mm and 1.25 mm (worst case), near acuity decreases though intermediate and distance visual acuities remained stable.


Raindrop Near Vision Inlay's centration is easily achieved by placing the inlay over the center of the light-constricted pupil. This task was achieved in 98% of cases. Clinically significant decentration (more than 0.9 mm) occurs infrequently (2%) and decreases near visual acuity without compromising intermediate or distance vision. FINANCIAL INTEREST: NONE
