Cataract Surgery

Cataract surgery is performed to treat cataracts. Cataracts can cause blurry vision and increase the glare from lights. If a cataract makes it difficult for you to carry out your normal activities, your doctor may suggest cataract surgery.

When a cataract interferes with the treatment of another eye problem, cataract surgery may be recommended. For example, doctors may recommend cataract surgery if a cataract makes it difficult for your eye doctor to examine the back of your eye to monitor or treat other eye problems, such as age-related macular degeneration or diabetic retinopathy.

In most cases, waiting to have cataract surgery won’t harm your eye, so you have time to consider your options. If your vision is still quite good, you may not need cataract surgery for many years, if ever.

When considering cataract surgery, keep these questions in mind:

  • Can you see to safely do your job and to drive?
  • Do you have problems reading or watching television?
  • Is it difficult to cook, shop, climb stairs or take medications?
  • Do vision problems affect your level of independence?
  • Do bright lights make it more difficult to see?

Cornea Transplant Surgery

A cornea transplant is most often used to restore vision to a person with a damaged cornea. A cornea transplant can also relieve pain or other signs and symptoms associated with cornea diseases.

A number of conditions can be treated with a cornea transplant, including

  • A cornea that bulges outward (keratoconus)
  • Fuchs’ dystrophy, a hereditary condition
  • Thinning or tearing of the cornea
  • Cornea scarring, caused by infection or injury
  • Swelling of the cornea
  • Corneal ulcers not responding to medical treatment
  • Complications caused by previous eye surgery

Glaucoma Surgery

Glaucoma surgery is a procedure intended to reduce eye pressure in an effort to help stabilize vision and prevent future vision loss resulting from glaucoma. This is accomplished by creating a new opening for fluid to drain from the eye — or, by implanting a shunt to help drain the fluid.

Although the surgery can lower eye pressure and help stabilize vision for a very long time, your doctors will still need to monitor your glaucoma during that time.

Recovery from glaucoma surgery is usually a simple and pain-free experience. Much depends on the type of procedure and your doctor’s expectations for the eye pressure recovery. Regardless, you will need to exercise some general precautions to assist with the healing process.

E.U.A

EUA is an examination under anaesthetic. You may need a general anaesthetic to allow your
doctor examine your back passage as it may be too uncomfortable to do so in the outpatient clinic
without sedation or a general anaesthetic. This is usually carried out as a day case procedure. You
will come to the Day ward on the morning of your procedure. You will usually be able to go home
the same day once you have recovered from your anaesthetic.
The purpose of having a EUA of rectum (back passage) is to investigate and treat, if possible certain
symptoms which you may be experiencing for example:

‐ Bleeding or discharge from your back passage
‐ Pain in your back passage
‐ Altered bowel habit eg. Diarrhoea/constipation

Optometry

Optometry is a healthcare profession that is autonomous, educated, and regulated (licensed/registered), and optometrists are the primary healthcare practitioners of the eye and visual system who provide comprehensive eye and vision care, which includes refraction and dispensing, detection/diagnosis and management of disease in the eye, and the rehabilitation of conditions of the visual system.

Eye examination

Following are examples of examination methods performed during an eye examination that enables diagnosis

  • Ocular tonometry to determine intraocular pressure
  • Refraction assessment
  • Retina examination
  • Slit Lamp Examination
  • Visual acuity

Specialized tests

Optical coherence tomography (OCT) is a medical technological platform used to assess ocular structures. The information is then used by eye doctors to assess staging of pathological processes and confirm clinical diagnoses. Subsequent OCT scans are used to assess the efficacy of managing diabetic retinopathy, age-related macular degeneration, and glaucoma.
