Purpose: To compare differences in visual outcomes and induced spherical aberration after conventional and wavefront-optimized LASIK for the treatment of hyperopia.
Methods: In a prospective, randomized, single-center clinical trial, 51 consecutive eyes underwent LASIK for the treatment of hyperopia. Eyes were divided between groups treated with conventional LASIK with the Alcon LADAR4000 excimer laser (n=25) and wavefront-optimized LASIK with the WaveLight ALLEGRETTO excimer laser (n=26).
Purpose: To compare the effect of femtosecond thinflap LASIK and photorefractive keratectomy (PRK) on postoperative endothelial cell density.
Methods: In a prospective, randomized, contralateral, single-center clinical trial, 25 patients (mean age: 30+/-5 years [range: 21 to 38 years]) underwent PRK in one eye and thin-flap LASIK in the fellow eye for the correction of myopia using a wavefront-guided platform. The central corneal endothelial cell density was measured using the NIDEK Confoscan 4 preoperatively, and at 1 and 3 months postoperatively.
Purpose: To investigate the association between ocular dominance and refraction.
Methods: A retrospective study of the cycloplegic refraction of 2453 consecutive patients with a mean age of 46 +/- 12 years (range: 18 to 79 years) was performed. One thousand one hundred fifty-seven (47%) patients were men and 1296 (53%) were women.
Purpose: To assess the long-term safety, efficacy, and stability of conductive keratoplasty (CK) in the treatment of presbyopia.
Methods: Ten near-plano presbyopic patients (6 women and 4 men) underwent unilateral CK with standard-pressure technique in the non-dominant eye to improve their near vision. Mean age was 51+/-3.
Purpose: Anterior segment optical coherence tomography (OCT) was used to analyze thin flaps created with the IntraLase femtosecond laser (IntraLase Corp).
Methods: Twenty-five eyes of 25 patients had flaps created with the 60 kHz IntraLase femtosecond laser prior to excimer laser ablation. The desired flap thickness was 110 microm with a diameter of 8.
Purpose: To assess the safety, efficacy, and stability of conductive keratoplasty (CK) in the treatment of presbyopia.
Methods: Ten near plano presbyopic patients (6 women and 4 men) underwent unilateral CK in the non-dominant eye to improve their near vision. Mean age was 51 +/- 3.
Purpose: To present our experience performing wavefront-guided ablations for the treatment of residual refractive error following previous refractive surgery.
Methods: Four different cases are presented-1) primary wavefront-guided LASIK; 2) wavefront-guided lift-flap LASIK retreatment; 3) wavefront-guided photorefractive keratectomy (PRK) retreatment; and 4) wavefront-guided PRK over radial keratotomy retreatment. All procedures were performed with the Alcon CustomCornea laser platform.
Purpose: To compare the measured difference and degree of cyclotorsion in eyes undergoing customized laser ablation between the time of wavefront measurement and laser refractive surgery.
Methods: The degree of cyclotorsion was measured in 1019 consecutive eyes of 732 patients who underwent wavefront-guided corneal ablation for the treatment of myopia with or without astigmatism with the Alcon LADARVision excimer laser. Prior to obtaining the wavefront measurement, the horizontal axis of each eye was marked.
