Abstract Details

Purpose:

Evaluate the safety and efficacy of combining corneal inlay implantation and laser vision correction using a dual-interface technique to extend depth of focus for myopic presbyopes.

Setting:

Global data registry(41 clinics in 18 countries)

Methods:

Retrospective analysis 7421 myopic presbyopes from 46 centers in 19 countries implanted monocularly with a small aperture inlay. Refractive error was treated using a standard LASIK procedure followed by inlay implantation into a femtosecond laser-created lamellar pocket. The manifest spherical equivalent refraction (MRSE), uncorrected near acuity (UCNVA), uncorrected distance acuity (UCDVA), and best-corrected distance acuity (BCDVA) were evaluated pre-operatively (n = 7421), week 1 (n= 7092), month 1 (n= 6784), month 3 (n= 6242), month 6 (n= 5644), month 12 (n= 4285) and month 18 (n= 2373). Visual acuity is represented in logMAR.

Results:

At 18 months, the MRSE in the inlay eye was -0.77D ± 0.79D. UCNVA improved 4 lines from 0.42 ± 0.29 at preop to 0.02 ± 0.13 at 18-months (p<0.0001). UCDVA improved to -0.01 ± 0.14 at 18-months from 0.05 ± 0.41 at preop (p<0.0001). 99.8% of patients achieved >20/25 BCDVA at 18 months. 0.36% experienced a sustained loss of 2 or more lines of BCDVA at 18 months. 90.4% of patients were within ±1.0D of target refraction. At 18 months, 88.2% and 77.2% of inlay eyes achieved 20/25 (J2) or better for distance and near respectively.

Conclusions:

Combining LASIK and small aperture inlay implantation using a dual-interface technique significantly improves uncorrected near and distance vision without compromising best-corrected distance vision in myopic presbyopes.
