CLINICAL SCIENCE Comparison of Custom Ablation and Conventional Laser InSituKeratomileusis forMyopiaandMyopicAstigmatism Using the Alcon Excimer Laser

چکیده
Methods: This was a prospective, nonrandomized, observational case series comparing outcomes of 239 eyes that underwent LASIK for myopia and myopic astigmatism with either wavefront or conventional ablation using the LADARVISION excimer laser. Manifest refractive sphere ranged from 0.50 D to 28.00 D with astigmatism up to 24.00 D. Eighty-nine eyes underwent conventional LASIK (conventional group), and 150 eyes underwent custom ablation (custom group). Refractive outcomes, ocular higher order root mean square (HOA-RMS), and contrast sensitivity were tested for statistically significant differences between groups. A P-value less than 0.05 was considered statistically significant. Six month postoperative data are reported here.

متن کاملThe Alcon/Summit/Autonomous perspective on fixed vs. variable spot ablation.
The LADARVision system utilizes a small fixed diameter excimer laser beam coupled with a high fidelity eye tracking system to perform wavefront-guided refractive surgery. The fixed small beam provides a consistent ablation per pulse. By delivering many identical pulses in a predetermined pattern, which includes an optimized custom blend zone, the laser is able to ablate complex (higher order) c...
متن کامل308-nm excimer laser plus topical calcipotriol in the treatment of vitiligo; A single blind randomized clinical study
Background: There is a large variety of therapeutic agents for the treatment of vitiligo, but it still remains a challenge. Narrow-band UVB phototherapy and 308-nm excimer laser have been shown to be safe and effective for the treatment of vitiligo. Topical calcipotriol has recently been reported to enhance the efficacy of phototherapy, especially 8-methoxypsoralen plus UVA (PUVA). The goal of ...
متن کاملStudy of laser ablation using nano-second laser pulses
In this paper, the laser ablation process based on the irradiation of nanosecond pulsed lasers on a copper target surface in the presence of Helium gas is studied. The dynamical behaviors of the generated plasma in the helium gas and evaporated copper at the atmospheric pressure are examined using a laser pulse, laser wavelength of and intensity of 7×1010W/cm2. A one-dimensional thermal model ...
