Abstract Details



Purpose:

To evaluate the safety and efficacy of implantation of a small aperture corneal inlay for presbyopia in emmetropic presbyopes.

Setting:

Asian Eye Institute, Philippines

Methods:

Prospective, non-randomized study of 13 patients implanted with a small aperture corneal inlay. The inlay was implanted monocularly in the non-dominant eye under a 200-?m flap, without any refractive treatment. To be included, patients needed to be between the ages of 45 and 60, and have a preoperative uncorrected near visual acuity (UCNVA) of worse than 20/40 and better than 20/100, binocular best-corrected distance visual acuity (BCDVA) of ?20/20, and a spherical equivalent between +0.50 and -0.75D.

Results:

Three years postoperatively, mean UCNVA in the inlay eye improved 3 lines from J6 to J2 by 1 month and was maintained out to 3 years. Binocular UCNVA improved 2 lines from J3 to J1 over the same time period. Mean monocular uncorrected intermediate visual acuity (UCIVA) improved 1 line, from 20/32 pre-operatively to 20/25 at 3 year follow up. Best-corrected distance visual acuity remained unchanged. Monocularly and binocularly, mean UCDVA remained constant at 20/20 and 20/16 respectively.

Conclusions:

In this small series, implantation of a small aperture corneal inlay under a 200-?m flap was an effective treatment for restoring near and intermediate vision in emmetropic presbyopes.
