Cataract surgery and IOL implantation have the safest and highest success rates of any eye care-related procedures. As with any type of surgery, however, some level of risk remains. [7] Most complications of cataract surgery do not result in long-term visual impairment, but some severe complications can lead to irreversible blindness. [92]
The cataract is removed from the capsule and anterior chamber using hydroexpression [Note 3] viscoexpression, [Note 4] or more-direct mechanical methods. [4] [13] [14] The extraction of the cataract must be done with due care so as not to compromise the integrity of the tunnel; the endothelium and capsule are also vulnerable to injury.
Prevalence of cataract considerably varies by age group, as well: for ages 50–59, it is 7.88%; for ages 60–69, it is 24.94%; for ages 70–79, it is 51.74%; in people over 80 years old, it is 78.43%. The overall cataract-surgery coverage rate was 9.19%. The prevalence of cataract and cataract surgical coverage also significantly varies by ...
Phacoemulsification is a cataract surgery method in which the internal lens of the eye which has developed a cataract is emulsified with the tip of an ultrasonic handpiece and aspirated from the eye. Aspirated fluids are replaced with irrigation of balanced salt solution to maintain the volume of the anterior chamber during the procedure.
However, a subsequent study conducted by the researchers from London School of Hygiene & Tropical Medicine and the Royal College of Surgeons of England confirmed the high quality of care, concluding that "patients undergoing cataract surgery or hip replacements in ISTCs achieved a slightly greater improvement … than those treated in NHS ...
Posterior capsular opacification, also known as after-cataract, is a condition in which months or years after successful cataract surgery, vision deteriorates or problems with glare and light scattering recur, usually due to thickening of the back or posterior capsule surrounding the implanted lens, so-called 'posterior lens capsule opacification'.
