Abstract Details

Purpose:

The aim of this prospective non-comparative study was to investigate the efficacy, predictability and stability of the CustomVue procedure using the new iDesign aberrometer (Abbott Medical Optics, Santa Ana, California) for treatment planning

Setting:

University Eye Clinic, Paracelsus Medical University, Salzburg, Austria

Methods:

This prospective non-comparative study included a total of 200 consecutive eyes with myopic astigmatism of 196 patients undergoing Wavefront Guided (WFG) LASIK surgery. A total of 90 patients (45%) were males and 90 females (55%). All eyes were treated with the excimer laser platform STAR S4 IR (Abbott Medical Optics, Santa Ana, CA) using the CustomVue procedure and the iDesign aberrometer for the profile calculation. Corneal flaps were created using the iFS femtosecond laser (Abbott Medical Optics, Santa Ana, CA). Mean patient age of the analyzed sample was 34 years (standard deviation, SD: 4.8; range 21 to 58 years). A comprehensive visual and ocular examination was performed preoperatively in all cases that included manifest and cycloplegic refraction, uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA). Postoperatively, patients were examined the day after surgery and then during follow-up visits at 1 week and 2 months after surgery. Change from baseline of HOA and Spherical Aberrations were measured after the 2 months follow up visit

Results:

At 2 months postoperatively, UDVA was 1.0 or better in 99 % (198 eyes). 78 % (156 eyes) achieved 1.2 UDVA. There was no loss of of 1 or more lines of CDVA, gains of 2 lines of CDVA were observed in 4% (8 eyes). Regarding predictability, at 2 months, 97 % (194 eyes) had a postoperative SE within ±1.00D and ±0.50D of emmetropia, respectively. There was no significant increase wavefront RMS and primary spherical aberration postoperatively. A significant decrease of total RMS values was found.

Conclusions:

The new iDesign Wavefront is an effective, safe and reliable software for treatment planning providing excellent refractive outcomes and good postoperative high order aberration results. FINANCIAL INTEREST: NONE
