Verdoorn C - A comparative scrutiny was performed of the visual performance and optical quality after Raindrop Near Vision Inlay implantation or monovision LASIK for the correction of presbyopia. It was determined that patients receiving corneal inlays exhibited better near and distance visual acuities, binocular stereopsis, task performance, and satisfaction, than patients treated with monovision LASIK.

Methods

• The plot of this trial was a retrospective case-series study.
• A comparative assessment was pursued of the patients previously treated in the nondominant eye with monovision LASIK, with patients previously implanted with Raindrop Near Vision Inlay.
• 16 inlay and 15 monovision LASIK patients were enrolled.
• A scrutiny was carried out of the uncorrected near visual acuity, uncorrected distance visual acuity, binocular stereopsis, patient satisfaction, and patient task performance.

Results

• The mean spherical equivalent was -0.66 D (0.78 SD) for the inlay group and -1.03 D (0.56 SD) for the monovision LASIK group, postoperatively.
• Monocularly, at uncorrected near distances, 60% of inlay patients and 47% of monovision LASIK patients achieved ≥20/20.
• It was unveiled that monocularly, at uncorrected far distances, 75% of inlay patients and 40% of monovision LASIK patients achieved ≥20/32 vision.
• 79% of inlay patients and 53% of monovision LASIK patients obtained ≥20/20 vision, binocularly, at near distances.
• It was deduced that all patients achieved ≥20/20 binocularly for distance.
• The inlay patients obtained 98 seconds of arc and monovision LASIK patients obtained 286 seconds of arc for stereopsis on average.
• A majority (79%) of the inlay patients and 66% of monovision LASIK patients reported satisfaction with their near vision.
• On the other hand, 86% of inlay patients and 67% of monovision LASIK patients displayed satisfaction with their distance vision.
