to present the results of a group of consecutive eyes with high hyperopia treated with LASIK and an Aberration neutral profile, and analyze the visual outcomes and corneal aberrations.
AURELIOS Augenzentrum Recklinghausen, Germany
We retrospectively analysed thirty consecutives eyes with 4 Diopters or more of nineteeen patients treated at the Augenzentrum Recklinghausen. The mean age was 41 years (range from 25 to 57). The mean preoperative Sphere was + 4.73 D (range 4 to 6.32 D), the mean cylinder was -1.32D (range from -4 to 0 D). At 3 months, a 100 % follow-up had been performed in all of the cases. All patients were examined preoperatively and at one day, one week, one month, and three months postoperatively.Corneal Aberrations were calculated at 6mm with the Videokeratoskopy (Keratron Scout,Opticon Italy), All surgeries were performed with the AMARIS 750S (Schwind eye-tech-solutions, Kleinhostheim, Germany) and the flap was created with the Carriazo Pendular Microkeratome (Schwind eye-tech.solutions, Kleinhostheim, Germany). The centration of the ablation was on the vertex of the cornea and the achieved postoperative keratometry should not be higher than 48 Diopters.
An overall increase in higher order aberrations was observed. We induced 150% of negative spherical aberration and 100% vertical trefoil.Other aberrtions as coma were not statistically significant. In terms of refractive outcomes 63% of the eyes were within ±0.50 D manifest refraction and 93% were within ±1.0 D at 3 months postoperatively. In terms of security one eye lost 2 Snellen lines and one eye gain 2 Snellen lines postoperatively
Hyperopic LASIK for higher hyperopia in selected cases is a safe and effective method. High hyperopic LASIK with optimized profiles and centration on the vertex induced cornea aberrations which are comparable to the aberrations that we induced with non-optimized profiles for low hyperopic LASIK.
