Abstract Details

Purpose:

To evaluate the visual performance of patients implanted with a small-aperture corneal inlay in a newly created lamellar pocket following a transepithelial PRK (TransPRK) performed with the Schwind Amaris excimer laser.

Setting:

Muscat Eye Laser Center, Oman.

Methods:

Four subjects underwent a monocular small-aperture corneal inlay insertion into a secondary lamellar pocket created with a femtosecond laser in the non-dominant eye one month after the TransPRK procedure. The target refraction for the TransPRK procedure was -0.50D. Monocular and binocular uncorrected distance, intermediate and near visual acuities (UDVA, UIVA, UNVA) were measured. Decimal acuity results are reported mean ± standard deviation. Outcomes data are currently available out to 12 months.

Results:

In the implanted eye, UNVA improved 5 lines from 0.24 ± 0.11 preop to 0.72 ± 0.10 at month 12. UCDVA remained constant, 0.86 ± 0.18 at preop and 0.90 ± 0.12 at month 12. UIVA improved 4 lines from 0.41 ± 0.07 at preop to 0.80 ± 0.00 at month 12. 100% of patients achieved 0.8 or better UDVA and UNVA binocularly at month 12. Mean manifest refractive spherical equivalent (MRSE) was -0.28D ± 0.21D at month 12. MRSE at all-time points were within ± 0.50D from achieved target refraction at month 1.

Conclusions:

The results from this study demonstrate excellent visual acuities and refractive stability in patients undergoing small aperture corneal inlay implantation following TransPRK for refractive correction. No intra-operative or post-operative complications were found. Further investigation of this technique is warranted.
