Laser in situ keratomileusis for hyperopia resulted in less regression, minimal haze, and better predictability and stability than surface photorefractive keratectomy. Preoperative corneal radius appeared to be an important factor in eyes with high hyperopia.

BACKGROUND A hospital-based study to evaluate the visual outcome after LASIK in patients of myopia. MATERIALS AND METHODS A total of 103 patients (200 eyes) with myopia and myopic astigmatism between-1.00 and-8.25 diopters (D) and up to-2.75 D astigmatism underwent LASIK treatment using the Carl Zeiss Meditec AG's MEL 80 (Germany) laser. The preoperative examination included assessment of UCVA and BCVA, slit lamp biomicroscopy, specular microscopy, non-contact tonometry, fundus evaluation, autokeratometry, corneal topography and corneal pachymetry. Patients were examined at 1 week, 1 month and 3 months following surgery. Parameters evaluated at each followup visit were Uncorrected Visual Acuity (UCVA), Best Spectacle Corrected Visual Acuity (BSCVA), residual refractive error and presence of any complications. RESULTS The mean preoperative UCVA (logMAR) improved from 1.203±0.289 to a value of 0.047±0.085 and 0.037±0.077 at the end of 1 month and 3 months postoperatively. A postoperative UCVA of 6/6 was achieved in 81% eyes, 6/9 in 17% eyes and 6/12 in 2% eyes at the end of 3 months when measured with the Snellen's visual acuity chart. The mean BCVA (logMAR) improved from 0.029 ± 0.066 to 0.025±0.063 and 0.023±0.060 at the end of 1 month and 3 months postoperatively; 87% eyes achieved a postoperative BCVA of 6/6, while 13% achieved a BCVA of 6/9. At the end of 3 months, the mean spherical equivalent of refraction was-0.24±0.369 compared to a preoperative mean of-4.81±2.053. A gain of one line of BCVA was seen in 5 eyes; 193 eyes retained their preoperative BCVA, while a loss of one line of BCVA was seen in 2 eyes. Postoperatively, dry eyes were found to be the most common problem followed by glare, striae and astigmatism. CONCLUSION For the correction of low-to-moderate myopia with lower degrees of astigmatism results from our study have shown that LASIK is effective and predictable in terms of obtaining very good-to-excellent uncorrected visual acuity.

Visual outcome after laser in situ keratomileusis (LASIK) in patients of myopia. J. Evolution Med. Dent. Sci. 2016;5(94):6932-6935, BACKGROUND Myopia is a common human ocular disorder. With its increasing prevalence and earlier age of onset in recent birth cohorts, myopia now affects almost 33% adults in US and epidemic proportions from 85% to 90% adults in Asian cities. 1 Single vision spectacle lenses and contact lenses are commonly prescribed for myopia and more recently refractive surgery has become a popular option. 2 In the history of refractive surgery, an important development has occurred in the use of excimer systems offering the possibility to change the anterior corneal refractive power through a controlled stromal ablation. 3
