Abstract

Introduction: As there is no pharmacological treatment for cataract, the standard treatment is surgical removal of the opacified lens and implantation of an artificial intraocular lens (IOL). The standard method of cataract extraction today is phacoemulsification. In this method, the crystalline lens is emulsified and aspirated away through a hollow needle that vibrates at high (ultrasonic) frequency, which is inserted through a centrally placed opening in the anterior capsular sac.
Methodology: Patient will then undergo phacoemulsification with implantation of a foldable posterior chamber intraocular lens, which will be done by a single surgeon, using the same technique. Patients will be randomly assigned to either of the two groups, ie hydrophilic acrylic foldable IOL and hydrophobic acrylic foldable IOL, until the target sample size has been achieved. The type of lens (hydrophilic/hydrophobic) will be noted for further studies.
Results: The first day postoperative vision is comparable between the two groups, with Hydrophilic lenses having visual outcome of 6/12 in 15 cases out of 40, and visual outcome of 6/9 in 12 cases out of 40, and Hydrophobic lenses having visual outcome of 6/12 in 17 cases out of 40, and visual outcome of 6/9 in 14 cases out of 40. (p value = 0.328).
Conclusion: Both IOL are equally beneficial in the visual rehabilitation of the patient.
