Purpose: To evaluate clinical outcomes after implantation of a corneal hydrogel inlay (Raindrop Near Vision Inlay) with concurrently performing laser in situ keratomileusis (LASIK) to correct presbyopia

Methods: Raindrop inlay (ReVision Optics, Inc., Lake Forest, CA, USA) was implanted at non-dominant eyes of 10 patients with presbyopia. Concurrent LASIK was performed for patients who have refractive error. Ophthalmologic evaluation included visual acuities at near, intermediate and far distance, higher-order aberration and complication cases. Subjective satisfaction was assessed by patient questionnaire.

Results: Compared to preoperative visual acuity, uncorrected near vision acuity (p=0.045) and far vision acuity (p=0.126) of inlay implanted eye was improved at one year after operation. There was no significant difference in the RMS total, coma and trefoil aberration between pre-operative and six month post-operative values. Almost patients were satisfied with task assessment at near, intermediate and far distance. However, two patients removed inlay at six months after operation due to subjective discomfort and another two patients removed inlay at one year after operation due to myopic shift.

Conclusions: Raindrop inlay implantation with concurrent LASIK effectively correct presbyopia. However, further long-term investigation about subjective discomfort and refraction change should be needed for confirmation of efficacy and safety.
