Clinical Outcomes With Presbyopia-Correcting Hydrogel Corneal Inlay: My Commercial Experience
Purpose
To report my clinical outcomes in presbyopes implanted unilaterally with Raindrop corneal inlay in the non-dominant eye with and without concurrent LASIK from a single center in Singapore.
Methods
Twenty-seven (n=27) patients were implanted with Raindrop Near Vision Inlay unilaterally in the non-dominant eye under a femtosecond flap centered over the miotic pupil. When needed, concurrent laser ablations were performed targeting a postop refraction of +0.75 D. Manifest refraction, distance (6 meters) and near (30 cm, 40 cm, and 50 cm) visual acuities were collected at preop, 1W, 1M, 3M, 6M, 9M, and 12M.
Results
Patients had an average age of 51 years (range: 35 to 63) at preop with average central corneal thickness of 554 microns. Femtosecond flaps were created at average thickness of 156 μm. 70% of patients required concurrent LASIK with average MRSE of -0.22 D and 30% required inlay only with average MRSE of +0.67 D. Interim data at 12M (n=6), monocular UDVA remained stable at 6/7.9. Monocular UNVA showed improvement from 6M to 12M with 100% of patients seeing N5 or better. All of patients (100%) at 12M were satisfied or very satisfied with this procedure.
Conclusion
Raindrop Inlay delivers very consistent near capability of N5 or better at near with high patient satisfaction. This inlay technology provides a valuable, effective tool in managing presbyopes in my practice. Results of my new study using mitomycin C during Raindrop implantation will be shared at the meeting.
