Long-Term Outcomes For Laser Vision Correction Utilising A Topography-Integrated Wavefront Guided Aberrometer

To evaluate the long-term safety and efficacy outcomes in patients who underwent laser vision correction on the Star S4 excimer laser guided by the iDesign 2.0 System.

Private Refractive Surgery (Optical Express)

Cohort consists of consecutive patients who underwent laser vision correction with iDesign 2.0 ablation and attended a clinical visit at one year postop. Clinical assessments, patient-reported outcomes, and any complications were recorded in an electronic medical record.

n=2,664 eyes of 1,371 patients with pre-op refractive range +5.25D to -10.75D with upto 5.50D of astigmatism. At one year postop, 89.0% had MSE within 0.50D of emmetropia & 97.3% within 1.00D. Attempted vs achieved cylinder of ±0.5D achieved in 87.8% of eyes. 83.1% of patients achieved binocular UCDVA 20/16 or better, 95.5% patients achieved binocular UCDVA of 20/20 or better and 99.9% 20/40 or better. 14 patient eyes (0.5%) had a loss in BCDVA of >2 lines, 320 (12.0%) had loss ≥1 line, 581 (21.8%) had gain ≥1 line. 90.8% of patients reported being very satisfied or satisfied with treatment & 92.6% would recommend to family & friends. No patients reported severe difficulty with sports or hobbies; 4.2% reported severe difficulty with QoV.

Long-term follow-up demonstrates that topography integrated wavefront guided laser vision correction is safe and effective. In addition to high levels of visual acuity gain, patient-reported satisfaction was also high. Incidence of complications was low and in line with other treatment formats. Long-term outcomes from a clinical and patient reported perspective are excellent.
