ABSTRACT

Background: Keratoconus is a chronic, bilateral usually asymmetrical, non-inflammatory disorder, being characterized by progressive steepening, thinning and apical scarring of the cornea which result in significant loss of vision. The classic treatment of visual rehabilitation in keratoconus is based on spectacles and contact lenses. Objective: To find out visual prognosis of keratoconus with scleral contact lenses. Method: A descriptive cross sectional study of 3 months had been carried out at “Keratoconus Pakistan (private specialized keratoconus clinic)” located in Rawalpindi Pakistan. Unaided visual acuity was measured with LogMAR visual acuity chart and then after complete evaluation of the case with the help of pentacam scan and slit lamp scleral contact lenses were fitted according to sagittal depth and keratometry readings and then with over refraction best corrected visual acuity was measured. Results: Total of 20 patients were examined, out of which (95%) were males and (5%) were females. (45%) were between the age of 15-25 years,(40%) were between the age of 26-35years,(15%) were between the age of 36-50years.(35%) patients were from the province of Punjab, (30%) were from Khyber Pakhtunkhwa,(20%) were from Sindh,(10%) were from Balochistan and (5%) were from Federal area of Pakistan. Out of total patients Unaided visual acuity from 6/9- 6/18 were (30%), 6/24-6/60 were (20%) and <6/60-counting fingers were (50%). Best corrected visual acuity of 6/6 were (55%), 6/9 were (30%) and 6/12 were (15%).Conclusion: In my study it was concluded that male patients were (95%) and female patients were(5%) and maximum patients were from the province of Punjab (35%). Scleral contact lenses are best option for the management of keratoconus because these lenses can provide best vision compared to other type of contact lenses with maximum comfort and wearing time. In most cases scleral contact lenses can be a best alternative to keratoplasty and other type of invasive corneal treatments and better visual results can be obtained after corneal cross linking (CXL).
