Optical Profile Following High Hyperopia Correction With a 500-Hz Excimer Laser System

Abstract

Correction of high hyperopia with LASIK significantly induces corneal higher order aberrations regardless of the physiologic level of photopic and mesopic pupil conditions.

Outcomes for Hyperopic LASIK With the MEL 90 ® Excimer Laser

“…Table A (available in the online version of this article) summarizes the preoperative key outcome measures of the studies that were identified. 9,10,15,[18][19][20][21][22][23][24][25][26][27]33 The UDVA results in the current study were similar to the results of hyperopic treatments with the MEL 80 and other modern excimer laser platforms. UDVA varied between 18% and 87% of eyes achieving 20/20 or better and between 84% and 100% of eyes achieving 20/40 or better after the primary treatment compared to 75% and 99% in the current study.…”

Small Incision Lenticule Extraction (SMILE) for Hyperopia: 12-Month Refractive and Visual Outcomes

“…However, it should be noted that the degree of hyperopia treated in the three FLEx studies was lower than most LASIK studies. The largest change of +0.72 D was for a 2-year time range 24 and two other studies 26,30 reporting a large change were for very high hyperopia. If these studies were excluded, the mean for LASIK was +0.18 D (range: 0.00 to +0.52 D).…”

Change in Corneal Tomography Following Femtosecond Laser–Assisted Lenticule Intrastromal Keratoplasty (LIKE) in Correcting Moderate to High Hyperopia

“…According to previous research reports, the EOZ diameter obtained after LASIK is significantly inversely proportional to the refractive correction 2. There is also higher refractive regression with higher hyperopic corrections 1–3. As such, it is speculated that refractive regression may be related to a smaller postoperative EOZ diameter.…”
