Wavefront-guided Laser In Situ Keratomileusis in the Treatment of High Myopia by Using the CustomVue Wavefront Platform

Abstract

The 3-month follow-up results of our study indicate that wavefront-guided LASIK by using the Visx S4 CustomVue wavefront platform is an effective, predictable, and safe treatment of high myopia.

Optical ray tracing–guided laser in situ keratomileusis for moderate to high myopic astigmatism

“…At 3 months, 85.6% (95 of 111 eyes) of eyes in our study had an SE within G0.50 D of the attempted SE. In the studies by Aizawa et al, 12 Bababeygy et al, 13 and Kulkamthorn et al, 14 the respective predictability was 64%, 70%, and 81%. Thus, in the treatment of moderate to high myopic astigmatism, optical ray tracing-guided LASIK tended to have higher predictability than in studies of wavefront-guided LASIK.…”

Visual acuity and higher-order aberrations with wavefront-guided and wavefront-optimized laser in situ keratomileusis

“…Overall, both lasers have been found to be safe and effective for the treatment of myopia and hyperopia. 3,[15][16][17] The LASIK surgeries were performed at Emory Vision, Atlanta, Georgia, USA, from December 2006 to December 2007. All LASIK flaps were created with an Amadeus II microkeratome (Ziemer Ophthalmics Systems AG) with a nasally placed hinge.…”

Managing Expectations in Refractive Surgery

“…These results have been widely verified by largescale, long-term, independent studies. 7,8 In contrast, excellent visual acuity outcomes in hyperopic astigmatism and mixed hyperopia are less common, regardless of the laser used. Far fewer patients reach UCDVA better than or equal to 20/20 postoperatively for these classes of refractive error, both in FDA studies and independent studies across the literature.…”

“…This is again true of both the FDA studies and independent studies following FDA approval. 8,14,15 Visual acuity and refractive outcomes may be moderately affected by the device used for both ablation (LASIK and PRK) and flap creation (LASIK). Various studies exist comparing excimer laser platform visual acuity results.…”

“…Many studies have shown that some percentage of patients will gain lines in best-corrected visual acuity following refractive surgery, but this is not true of a majority of patients. 7,8 Setting appropriate patient expectations for the rate at which vision will improve as well as any secondary symptoms, no matter how temporary, is key. LASIK patients often expect to achieve maximal UCDVA on postoperative day 1; however, it can be important to reassure patients postoperatively that ocular surface dryness may temporarily limit postoperative vision.…”
