Complications after cataract surgery are relatively uncommon. Posterior vitreous detachment (PVD) may occur but does not directly threaten vision. [23] Some people develop a posterior capsular opacification (PCO), also called an after-cataract. This may compromise visual acuity, and can usually be safely and painlessly corrected using a laser.
A phakic intraocular lens (PIOL) is an intraocular lens that is implanted surgically into the eye to correct refractive errors without removing the natural lens (also known as "phakos", hence the term). Intraocular lenses that are implanted into eyes after the eye's natural lens has been removed during cataract surgery are known as pseudophakic.
Nontoxic, sterile, and does not affect intraocular pressure; Does not obstruct aqueous outflow; Optically clear, allowing an unobstructed view. Easy removal, or no removal required after use; The most relevant physical properties for use in ophthalmic surgery are viscoelasticity, viscosity, pseudoplasticity, and surface tension. [2]
LASIK or Lasik (/ ˈ l eɪ s ɪ k /; "laser-assisted in situ keratomileusis"), commonly referred to as laser eye surgery or laser vision correction, is a type of refractive surgery for the correction of myopia, hyperopia, and astigmatism. [1]
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 ...
Complications after cataract surgery are relatively uncommon. Posterior vitreous detachment (PVD) does not directly threaten vision, but may increase the risk of future vitreoretinal conditions. It may be more problematic in younger eyes because many people older than 60 have already gone through PVD.
