| Title | Improving refractive laser surgery outcomes by using Relex Smile for intermediate and high myopia and myopic astigmatism |
| Abstract Nr. | 1041 |
| Purpose | To report the results of the first 150 treated eyes of small incision lenticule extraction (Relex Smile) for myopia and myopic astigmatism using the Carl Zeiss Meditec 500 kHz Visumax Femtosecond laser. |
| Methods | Method: Using the Zeiss 500 kHz Visumax Femtosecond laser for correction of myopia and myopic astigmatism, a small stromal lenticule is created, dissected using an Shanzu dissector, and extracted through a 3.5 mm sidecut using a 0.12 forceps. After the procedure, the lenticule was inspected for possible defects. Advantages compared to femtolasik are the lack of influence of room temperature, room humidity, and air current. The treatment also takes place in a closed environment which should improve accuracy. Outcome measures were corrected distance visual acuity (CDVA), uncorrected distance visual acuity (UDVA), and manifest refraction during 3 months of follow-up. Pentacam topography was performed at each visit. |
| Results | 150 eyes were treated. The average age at surgery was 35 years. 52 % male and 48 % female patients. Pre SR equiv was -5.37 +/-1.65 D. Pre SR sph -4.95 +/- 1.64 D, pre SR cyl -0.84 +/- 0.54 D. At 3 weeks, post SR equiv was -0.06 +/- 0.58 D. Post SR sph 0.18 +/- 0.57 D, post SR cyl -0.48 +/- 0.29 D. No patients lost more than one line of BCVA. 2 % gained more than one line of BCVA. 85 % had a refractive outcome between +/- 0.5 D of attempted refraction, and 95 % between +/- 1.0 D of attempted refraction. 91 % had an UCVA of 0.8 or more. |
| Conclusion | The results of Relex Smile for myopia and myopic astigmatism, a flapless and minimally invasive technique using only an femtosecond laser without need for an excimer laser, are excellent, and comparable to the highest standard of modern Femtolasik techniques. Larger studies are ongoing. |
