N2 - PURPOSE: To report the results in the first 100 eyes treated for myopia using a new advanced nomogram. SETTING: Private refractive surgery clinic. METHODS: This prospective interventional case series comprised 58 patients (100 eyes) consecutively treated for myopia with laser in situ keratomileusis (LASIK) or laser-assisted subepithelial keratectomy (LASEK) performed by the same surgeon. All treatments used a new nomogram for the Zyoptix 217 Z100 excimer laser. Postoperative mean sphere, cylinder, and spherical equivalent (SE) refraction were evaluated 3 months postoperatively. Safety, efficacy, and predictability were also evaluated. RESULTS: In the LASIK group (34 eyes), the mean postoperative sphere was +0.18 diopters (D) +/- 0.47 (SD), the mean postoperative cylinder was -0.10 +/- 0.23 D, and the mean postoperative SE was 0.04 +/- 0.36 D. In the LASEK group (64 eyes), the respective means were 0.10 +/- 0.22 D, -0.05 +/- 0.13 D, and + 0.03 +/- 0.16 D. Hyperopic overcorrection (>= + 1.00 D) occurred in 4.1% of patients. Ninety-five percent of eyes in the LASIK group and 97% of eyes in the LASIK group had an uncorrected visual acuity of 1.0 (20/20) or better, Patient satisfaction was slightly higher than that of other laser refractive surgery patients at the clinic. CONCLUSIONS: The use of the advanced nomogram increased treatment accuracy in terms of UCVA and postoperative mean refraction and reduced the rate of hyperopic overcorrection over that in earlier studies. The need for enhancement procedures was reduced, and patient satisfaction was high
