Abstract Details

Purpose:

Evaluate the effectiveness of combining hyperopic LASIK and corneal inlay implantation to extend depth of focus for hyperopic presbyopes.

Setting:

Crystal Clear Vision Canada, 33 Hazelton Avenue, Toronto, Canada

Methods:

Retrospective analysis of 2022 hyperopic presbyopes treated at 16 centers in 10 countries. A small aperture corneal inlay was implanted monocularly into the non-dominant eye into a secondary lamellar pocket subsequent to bilateral laser vision correction. Manifest spherical equivalent refraction (MRSE), uncorrected (U) near (N) and distance (D) visual acuity (VA), and best-corrected (BC) DVA were evaluated pre-operatively (n = 2022), week 1 (n= 1678), month 1 (n= 1822), month 3 (n= 1688), month 6 (n= 1413), month 12 (n= 997) and month 18 (n= 502). Visual acuity is represented in Snellen.

Results:

UCDVA improved from 20/21 at preop to 20/17 at 18-months (p<0.0001). UCNVA improved 4.5 lines from 20/78 at pre-op to 20/28 at 18-months (p<0.0001). At 18 months, the MRSE in the inlay eye was -0.40 ± 0.63. 100% of patients achieved a BCDVA of >20/25 at 18 months. 0.22% experienced a sustained loss of 2 or more lines of BCDVA at 18 months. 95.8% of patients were within ±1.0D of target refraction.

Conclusions:

Combining hyperopic laser vision correction and small aperture inlay implantation extends depth of focus by significantly improving both uncorrected near and distance visual acuity in treated eyes.
