Cataract surgery is the most common application of lens removal surgery, and is usually associated with lens replacement. It is used to remove the natural lens of the eye when it has developed a cataract, a cloudy area in the lens that causes visual impairment. [ 4][ 10] Cataracts usually develop slowly and can affect one or both eyes. [ 4]
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.
Manual small incision cataract surgery (MSICS) is an evolution of extracapsular cataract extraction (ECCE); the lens is removed from the eye through a self-sealing scleral tunnel wound. A well-constructed scleral tunnel is held closed by internal pressure, is watertight, and does not require suturing. The wound is relatively smaller than that ...
Sympathetic ophthalmia ( SO ), also called spared eye injury, is a diffuse granulomatous inflammation of the uveal layer of both eyes following trauma to one eye. It can leave the affected person completely blind. Symptoms may develop from days to several years after a penetrating eye injury. It typically results from a delayed hypersensitivity ...
Irvine–Gass syndrome, pseudophakic cystoid macular edema or postcataract CME is one of the most common causes of visual loss after cataract surgery. [ 1][ 2] The syndrome is named in honor of S. Rodman Irvine [ 3][ 4] and J. Donald M. Gass. [ 5] The incidence is more common in older types of cataract surgery, where postcataract CME could ...
The procedure results in a decrease in nearsightedness. According to the PERK study, 58% of eyes were corrected within 1.00D of goal 3 years after surgery. Additionally, 76% of eyes had uncorrected vision of 20/40 or better at 3 years. [5] From 2 to 10 years post-operatively 43% of eyes had an increase in farsightedness by 1.00D or more.
Intraocular lens. An Intraocular lens ( IOL) is a lens implanted in the eye usually as part of a treatment for cataracts or for correcting other vision problems such as short sightedness and long sightedness; a form of refractive surgery. If the natural lens is left in the eye, the IOL is known as phakic, otherwise it is a pseudophakic lens (or ...
Long term risk of retinal detachment after extracapsular and phacoemulsification cataract surgery at 2, 5, and 10 years was estimated in one study to be 0.36%, 0.77%, and 1.29%, respectively. [ 12 ] Tractional retinal detachments can also occur in patients with proliferative diabetic retinopathy [ 13 ] or those with proliferative retinopathy of ...
