Contact Lens Analysis: Optometry and Vision Science - Case Study Example

The very first case under observation to deal with the problems of contact lenses was taken to be of a 32 years old male who was diagnosed with binocular keratoconus which causes progressive deterioration in vision and leads to further thinning and distortion of the cornea which causes reduced vision, blurred distance vision, glare, and disturbing night vision as well, however, use of proper contact lenses can help in maintaining good functional vision (Kymes S, Walline J, Zadnik K, Gordon M. viewed on 30th October 2008).

The patient suffered from the problem in 2004 with measurements of visual acuity in the right eye as 6/60¯ and in the left eye as 6/60¯. Past research has supported the fact that binocular entrance visual acuity worse than 20/40, is generally linked with a lower quality of life scores except in maintaining general health and ocular pain (Kymes S, Walline J, Zadnik K, Gordon M. viewed on 30th October 2008).Contact Lens DetailsThe past history of the patient revealed that he was wearing KBA contact lenses since 22nd November 2006 with parameters in the right eye measuring eccentricity as 1.

15, base curve 6.44 mm, diameter 10.2 mm, power -12.25D, periphery BOSTON XO, marked “R”, tint blue and the Left eye measurement showed an eccentricity 0.96, base curve 6.96 mm, diameter 10.2 mm, power -8.00D, periphery BOSTON XO, marked “L”, tint blue.The Visual acuity with his lenses in the right eye was 6/7.5 and in the left eye were 6/9+3. The patient did complain about fogging in his left eye and at the same time, the right eye was found with proper functioning and absence of any sort of ailment or discomfort.

The patient was wearing these lenses on an extended wear basis and was able to manage comfortably wearing the lens in his right eye for a longer period in comparison to his left eye. The cleaning solution used by the patient was Simplus Multi-Action Solution from Bausch and Lomb which is safe and effective as it helps in the removal of accumulated proteins and is easy to use as well. Its cleaning system helps in the removal of dirt and deposits from the contact lenses destroying the microorganisms and aiding a wetting and a cushioning system.
