ABSTRACT
Introduction: Refractive error has now become the secondmost common cause of blindness across the world. Thereis necessity to explore the various factors having impact onrefractive errors as they will certainly assist in the variousmodes of treatment aspect of the refractive errors. This studywas carried out with the aim of comparing refractive errorwith axial length in the subjects with refractive error.Material and methods: In this study, total of 500 adult caseswere recruited. So total of 1000 eyes were examined upon.This study was carried out, over a total period of 2 years.General examination was carried out in each and every case.Afterwards, local examination was done. Then refractive errorand axial length was measured. The data obtained from thisstudy was analysed statistically.Results: The results of our present study have showed thatthe spherical refractive error has statistically highly significantnegative correlation with axial length, in right eye (r=-0.836,p<0.01) and in left eye (r=-0.859, p<0.01).Conclusion: The observation made from this study says thaton progressing from myopic to hyperopic refractive error, theaxial length of the eye is found to decrease. In the refractiveerror of shortsightedness or myopia, the final image is formedahead of retina
ABSTRACT
LASIK is the most popular treatment method for correction of the refractive errors of ophthalmology its development in 1990 and number of patients has continued to increase.The safety and efficacy of LASIK surgery have been reported several times by numerous researchers and doctors, but all studies have made abroad. This time we have summarized postoperative outcomes of LASIK surgery, which have performed in our country. Consequently 103 patients (206 eyes) who underwent LASIK surgery in “Bolor-Melmii” eye clinic between 2007 and 2011 were enrolled. The retrospective method of study was used to evaluate postoperative outcomes. Preoperative UCVA of 0.04-0.4 improved to 0.5-1.2(decimal) at 1 day after surgery and during 1 year after surgery revealed minimal but wasstable. Preoperative mean sphere equivalent of 2.2+/-0.72D improved at the 1 year by +/-0.5D in 161 eyes (78.15%), by +/-1.0D in 39 eyes (18.9%) and by +/-2.0D in 6 eyes (2.9%)after surgery. Mean sphere equivalent and astigmatism improved to -0.46 +/-0.4D and -0.43+/-0.34D respectively at 1 year after surgery. Improvement of the sphere equivalent and its stability during a year period of study proves that LASIK surgery is an effective with stable improvements and safe procedure for correcting myopia/myopic astigmatism. No severe complications occurred during and after surgery.
