Outcomes also improving
We know that LASIK outcomes were already very good, but the new aberrometry technology has made them even better.
Analysis of a large number of eyes (11,000) treated with iDesign-guided LASIK at laser vision correction centers in the United Kingdom revealed that 97.4% of patients said they were satisfied/very satisfied with their uncorrected vision after surgery, a number that was statistically significantly higher than the percentage giving that response after WaveÂScan-guided LASIK.
The share of eyes seeing 20/20 or better and 20/16 or better was significantly higher with iDesign than with the WaveScan, as was the percentage of eyes with better postoperative uncorrected vision compared to their preoperative best-corrected vision.
A recent paper in which iDesign-guided LASIK was compared to small lenticule extraction (SMILE) found that 98% of the LASIK eyes, versus only 82% of the SMILE eyes, achieved a postoperative spherical equivalent within 0.50 D.1 There was no loss of lines of corrected distance acuity in the LASIK eyes, compared to 6.8% of the SMILE eyes.
