“…Excimer laser systems have recently been developed with innovative features, such as high repetition rates (400 and 500 Hz) and customized ablation profiles 1,6,11–14. These enhanced features have improved the effectiveness and safety of LASIK surgery, thus making treatment possible for a broad range of patients, including those with moderate-to-relatively high hyperopia.…”

“…It has been shown that higher repetition rates may provide better ablation quality vs slower systems 15. This improvement in ablation quality is thought to be due to a decrease in stromal dehydration, flap shrinkage, fixation fatigue, and sensitivity to eye movements 1,2,16…”

“…The advancement of technology in excimer lasers has changed the stability and regression of hyperopic corrections, resulting in US Food and Drug Administration (FDA) approval of the WaveLight Allegretto 400 and EX500 systems of up to 6.00 diopters (D) of hyperopia/hyperopic astigmatism correction 1–3. This was primarily due to a wide optical zone of ablation, rapid ablation times from high repetition rates, and faster, more accurate eye scanners.…”

PurposeTo evaluate the efficacy of treating patients with +3.00 diopters (D) to +6.00 D of hyperopia via laser-assisted in situ keratomileusis (LASIK) with the WaveLight Allegretto 400 and EX500 excimer laser systems.SettingPrivate clinical ophthalmology practice.Patients and methodsThis was a retrospective study of patients undergoing LASIK treatments of +3.00 to +6.00 D on two different WaveLight laser systems: 163 eyes on the 400 (Hertz) Hz system and 54 eyes on the 500 Hz system. The duration of follow-up was 6 months postoperation. Data were evaluated for uncorrected distance visual acuity, corrected distance visual acuity (CDVA), spherical equivalents (SEQs), and changes in these parameters (eg, loss of vision, regression over time).ResultsTreatment with both lasers was safe and effective, with loss of one line of CDVA in four of 162 eyes using the 400 Hz laser system, and none of the 54 eyes with the 500 Hz laser system. Overall, regression ≥0.75 D from goal at 6 months was observed in 11.7% (19/163) of eyes in the 400 Hz laser group and 9.26% (5/54) of eyes in the 500 Hz laser group (regression ≥0.50 D =77.9% [127/163] and 77.8% [42/54], respectively). The mean SEQ regressions for all eyes with moderate hyperopia were 0.10 and 0.18 D for those with high hyperopia.ConclusionsBoth the 400 and 500 Hz excimer laser systems were safe and effective for the LASIK treatment of moderate-to-high hyperopia. The overall rate of regression was low and the amount of regression was relatively small with both systems.

“…14,15 Reports from the past 15 years have shown continued improvement in safety and accuracy with the use of wavefront-guided and wavefront-optimized systems being used to treat myopic astigmatism as high as −10.00 to −12.00 D. These trials have reported up to 100% of eyes achieving refractions within 1 D of emmetropia. 16–18 …”
