AIM: To determine the efficacy, stability and higher order aberrations (HOAs) following Zyoptix Tissue-Sparing (TS) and conventional Planoscan LASIK. METHODS: A prospective study was conducted on myopic patients. The Technolas 217z laser and XP microkeratome (Bausch & Lomb) were used. Patients were matched for age, pupil size, optical zone, ablation depth and preoperative HOAs. UCVA, MRSE and HOAs were analysed preoperatively and 3 and 12 months postoperatively. RESULTS: 35 eyes underwent conventional and 31 eyes TS LASIK. 3 months postoperatively, all eyes in the both groups had UCVA < or =20/30 with good stability at 1 year. The mean RMS of total HOA increased significantly 3 months postoperatively in the conventional (1.49 factor increase) and TS LASIK groups (1.84 factor increase) and remained stable at 12 months. CONCLUSION: TS LASIK induced a greater increase in HOA than conventional Planoscan LASIK. This may be attributable to the smaller blend zone in TS treatments.
