Cataract Eye : Diagnosis and Treatment

Initially, In a Cataract Eye a cataract may be asymptomatic, but after some time they can enlarge and influence vision severely.As stated by World Health Organization cataracts are the most widely recognized reason for visual impairment in the world.As cataracts are strongly related to aging, so there is no real way of their prevention.Fortunately, once cataracts are diagnosed, they can be treated effectively with surgery.

Cataract Diagnosis

An extensive eye exam is required for diagnosing cataracts readily. This exam incorporates the following tests:

Diagnosis

Refraction and visual acuity test

This test evaluates the clarity and sharpness of your vision, and your ability to see at various distances.

Slit-lamp exam

In this test, a specialized magnifying glass is utilized by your eye specialist to see abnormalities.

Retinal exam

Your ophthalmologist looks at your retina with the help of a specialized instrument after dilatation of your eyes with a drug.

Your specialist may likewise test the intraocular pressure in your eyes, and also your color vision and sensitivity of glare.

Cataract surgery

Surgery is right now the best and only possible way to treat cataracts. There are two primary kinds of surgery

Surgery

Phacoemulsification:

This is the most commonly performed surgical procedure to treat cataracts.

The cornea is the outermost clear dome-shaped covering of the eye. Your eye specialist will first make a small incision into the side of your cornea.

A needle-thin probe is then inserted into your eye that radiates high-frequency ultrasound. These radiations break the lens into tiny pieces, enabling it to be suctioned out.

In this procedure, the outer membrane of the lens, lens capsule, is left intact.

Extracapsular surgery:

In this method, a bigger incision is made into your cornea by your ophthalmologist. This is followed by the opening of lens capsule and expulsion of the center of the lens as a whole.

In this surgery, only the posterior part of your lens capsule is left intact.

After the expulsion of the lens through either of the two surgeries, your ophthalmologist will place an artificial lens, called an intraocular lens (IOL).

IOL can be made of clear plastic, silicone, or acrylic material. It is permanent and can be customized to suit your vision needs.

The results of cataract surgery are promising as indicated by the American Optometric Association with around 90 percent of individuals revealing enhanced vision afterward.

Cataract Surgery Risks

Complications of cataract surgery are very rare. However in uncommon cases complications that can occur include:

  • Bleeding in the eye
  • Eye infection
  • Glaucoma
  • Drooping of the upper eyelid
  • Retinal separation, in which the retina is lifted or pulled from its typical position
  • Swelling of the cornea
  • Fluid collection in the retina
  • Partial or full loss of vision
  • Double vision

Issues with the IOL can likewise happen, for example, dislocation of the lens and secondary cataract, a condition in which the cloudiness occurs in lens capsule and vision becomes blurred.

Cataract Surgery Recovery

You’ll have the capacity to go home after your surgery — a stay at the hospital isn’t required — however you won’t have the capacity to drive on the day of your surgery.

Your specialist may likewise suggest that you avoid lifting articles or bending for a couple of days.

During the recovery period, you may experience following symptoms in the operated eye:

  • Itching
  • Discomfort in the eye
  • Discharge
  • Sensitivity to light and touch

In spite of these issues, it’s vital to abstain from rubbing or putting pressure on your eye.

You may need to oftentimes wear an eye shield or shades to protect your eye.

Your specialist may recommend eye drops for prevention of infection and control of eye pressure.

Most patients completely recover within two months after cataract surgery, as indicated by the National Eye Institute.
