What are the complications of cataract extraction?

When cataract surgery complications do occur, they can include:

• Posterior capsule opacification (PCO)
• Intraocular lens dislocation.
• Eye inflammation.
• Light sensitivity.
• Photopsia (perceived flashes of light)
• Macular edema (swelling of the central retina)
• Ptosis (droopy eyelid)
• Ocular hypertension (elevated eye pressure)

What is the most common complication of cataract surgery?

A long-term consequence of cataract surgery is posterior capsular opacification (PCO). PCO is the most common complication of cataract surgery. PCO can begin to form at any point following cataract surgery.

What is the difference between cortical and nuclear cataract?

Cortical Cataracts start the reverse of the Nuclear Sclerotic Cataracts. It starts from the outer most layer of the eye. As it progresses it creates spokes that lead from the outside of the lens to the nucleus.

What happens when cataracts are removed?

After cataract surgery, expect your vision to begin improving within a few days. Your vision may be blurry at first as your eye heals and adjusts. Colors may seem brighter after your surgery because you are looking through a new, clear lens.

What are the risks of YAG laser capsulotomy?

Risks

• Detachment of the nerve layer at the back of the eye (retinal detachment).
• Swelling of the center of the retina (macular edema).
• Damage or displacement of the intraocular lens.
• Bleeding into the front of the eye.
• Swelling of the clear covering of the eye (corneal edema).

What are the disadvantages of laser cataract surgery?

The major disadvantages of femtosecond laser-assisted cataract surgery are high cost of the laser and the disposables for surgery, femtosecond laser-assisted cataract surgery-specific intraoperative capsular complications, as well as the risk of intraoperative miosis and the learning curve.

What are the restrictions after cataract surgery?

Don’t drive on the first day following surgery. Don’t do any heavy lifting or strenuous activity for a few weeks. Immediately after the procedure, avoid bending over to prevent putting extra pressure on your eye. If at all possible, don’t sneeze or vomit right after surgery.

What happens nuclear cataract?

What is Nuclear Cataract? An excessive amount of yellowing and light scattering affecting the centre of the lens is called nuclear cataract. The nuclear sclerosis is when the nucleus, i.e. the center of the eye, begins to get cloudy, yellow, and hardens.

What are nuclear cataracts?

Nuclear cataracts are a clouding and hardening of the lens center, resulting in blur, glare and other changes in vision. They are the most common type of cataract. In a study of people aged 75 years and older, the occurrence of nuclear cataract in at least one eye was 40\%.

Can YAG laser cause vision problems?

Perhaps the greatest risk posed from the YAG procedure is the chance of getting a detached retina. A retinal detachment occurs about two percent of the time from the laser procedure. Alert your ophthalmologist if you have any of the symptoms that include: Clouded vision.

How safe is YAG laser surgery?

NdYAG capsulotomy is generally a safe and successful method in relieving the symptoms of posterior capsular opacification. Documented complications include, transient rise in intraocular pressure,2 retinal detachment,3 lens subluxation or dislocation,4 lens pitting,5 and exacerbation of local endophthalmitis.

Is laser-assisted cataract surgery worth it?

Both methods are extremely successful and safe.” To translate that into simpler terms, on average, the evidence suggests that patients who have laser-assisted cataract surgery tend to see about as well as patients who have traditional cataract surgery. Not significantly better, or worse.

What is a posterior subcapsular cataract?

Posterior subcapsular (PSC) cataract presents at the back of the lens just in front of the posterior capsule ( Fig. 6.25 ). In the age-related vacuolar type of PSC cataract, localised reductions in refractive index and vacuoles are found in the early stages.

What is involved in cataract surgery?

Cataract surgery typically involves removing the cataract and clouded lens of the eye, and replacing it with an artificial lens, usually an intraocular lens (IOL). Nuclear, cortical, and posterior subcapsular cataracts can all be treated with cataract surgery, which typically takes about an hour or so.

What are nuclear cataracts in the eye?

Nuclear Cataracts Nuclear cataracts are often a normal progression of aging, as the lens of the eye can yellow and become cloudy with age. A nuclear cataract is most often associated with aging and forms in the center of the lens (the nucleus). Nuclear cataracts can occur in one or both eyes, and they often impact distance vision.

What is the difference between sclerotic cataracts and cortical cataract?

Cortical Cataracts start the reverse of the Nuclear Sclerotic Cataracts. It starts from the outer most layer of the eye. As it progresses it creates spokes that lead from the outside of the lens to the nucleus. The symptoms of this cataract are blurred vision, difficulty with glare, and changes in both contrast and depth perception.
