Cataract Clinical Trial
Official title:
Auditing of Poor Visual Outcomes After Un-eventual Cataract Surgery: a Prospective Cohort Study
Globally, cataract is the major cause of blindness accounting for 51% of total blindness and
there are regional variations in it. Today, cataract surgery is a highly successful and
cost-effective procedure, which enhances both the vision and quality of life of patients.
Visual acuity alone should not be used as a criterion for planning cataract surgery, since
visual acuity and function do not necessarily correlate. Therefore, there is a need to review
our criteria for management.
Based on recent studies, at least 90% of the patients undergoing cataract surgery obtain a
postoperative visual acuity of 6/12 or better in the absence of coexisting ocular pathology.
A number of previous studies have looked at the effect of risk factors on visual outcomes
following cataract surgery. Risk factors commonly associated with worse visual outcomes
include: age-related macular degeneration, diabetic retinopathy, corneal opacity/pathology,
older age, female sex, previous vitrectomy, previous retinal detachment surgery,
alpha-blockers, complex surgery, intraoperative complications and refractive surprise.
