Cataract Surgery: Risk, Preparation, and what to expect

Cataract surgery is a surgical procedure that removes your eye's lens and, in most cases, replaces it with an artificial lens. Normally, your eye's lens is clear. A cataract causes the lens to become cloudy, affecting your vision. Cataract surgery is performed on an outpatient basis by an eye doctor (ophthalmologist), which means you do not need to stay in the hospital after the procedure. Cataract surgery is a common and relatively safe procedure.

Why Is Cataract Surgery Done?

To treat cataracts, cataract surgery is performed. Cataracts can cause blurry vision and increased light glare. If a cataract interferes with your daily activities, your doctor may recommend cataract surgery.

Cataract surgery may be recommended if cataract interferes with the treatment of another eye problem. For example, 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, doctors may recommend cataract surgery. A standard eye cataract surgery cost ranges from $3000 to $5000 per eye. The exact cataract surgery cost often depends upon the location of the facility.

In most cases, delaying cataract surgery will not harm your eye, giving you more time to consider your options. If you have good vision, you may not need cataract surgery for many years, if ever. Consider the following questions when considering cataract surgery:

  1. Can you see well enough to do your job and drive safely?
  2. Do you struggle to read or watch television?
  3. Is it challenging for you to cook, shop, do yard work, climb stairs, or take medication?
  4. Do your vision problems limit your independence?
  5. Do bright lights make it harder to see?

Risks

Complications following cataract surgery are uncommon, and the majority can be successfully treated. Risks associated with cataract surgery include:

  • Inflammation
  • Infection
  • Bleeding
  • Swelling
  • eyelid drooping
  • Artificial lens dislocation
  • Detachment of the retina
  • Glaucoma
  • Cataract secondary
  • Visual impairment

If you have another eye disease or a serious medical condition, your risk of complications increases. Cataract surgery may fail to improve vision in some cases due to underlying eye damage caused by other conditions such as glaucoma or macular degeneration. If possible, it may be advantageous to evaluate and treat other eye problems before deciding on cataract surgery. The eye cataract surgery cost in Mauritius often ranges from MUR 8,500 to MUR 45,700.

Preparing For The Procedure

You may be told not to eat or drink anything for 12 hours prior to cataract surgery. Your doctor may also advise you to discontinue any medications that may increase your risk of bleeding during the procedure for a short period of time. Inform your doctor if you are taking any medications for prostate problems, as some of these medications may interfere with cataract surgery.

One or two days before surgery, antibiotic eye drops may be prescribed. You can usually go home the same day as your surgery, but you won't be able to drive, so make arrangements for a ride home. Arrange help around the house if necessary, as your doctor may restrict activities like bending and lifting for about a week after your surgery.

What To Expect Before The Procedure

Your doctor will perform a painless ultrasound test to measure the size and shape of your eye about a week before surgery. This aids in determining the best type of lens implant (intraocular lens, or IOL). IOLs will be given to nearly everyone who has cataract surgery. By focusing light on the back of your eye, these lenses improve your vision. The lens will be invisible to you.

It requires no maintenance and becomes an indelible part of your vision. There are several IOLs with different features available. You and your eye doctor will discuss which type of IOL is best for you and your lifestyle before surgery. Cost is another consideration, as insurance companies may not cover all types of lenses.

Among the various types of lenses available are:

Monofocal with fixed focus - For distance vision, this lens has a single focus strength. Reading glasses are usually required when reading.

Monofocal with accommodating focus -Despite having only one focusing strength, these lenses can respond to eye muscle movements and shift focus to near or distant objects.

Multifocal - These lenses are similar to bifocal or progressive lenses in glasses. The lens has different focusing strengths in different areas, allowing for near, medium, and far vision.

Correction of astigmatism (toric) - A toric lens can help correct your vision if you have significant astigmatism.

Discuss the advantages and disadvantages of the various types of IOLs with your eye surgeon to determine which is best for you.

What To Expect During The Procedure

Cataract surgery, usually an outpatient procedure, takes an hour or less to perform. First, your doctor will place eyedrops in your eye to dilate your pupil. You'll receive local anesthetics to numb the area, and you may be given a sedative to help you relax. If you're given a sedative, you may remain awake, but groggy, during surgery. During cataract surgery, the clouded lens is removed, and a clear artificial lens is usually implanted. In some cases, however, a cataract may be removed without implanting an artificial lens. Surgical methods used to remove cataracts include:

Cataract surgery, which is typically performed as an outpatient procedure, takes an hour or less to complete. To begin, your doctor will insert eye drops into your eye to dilate your pupil. Local anesthetics will be used to numb the area, and you may be given a sedative to help you relax. You may be awake but groggy during surgery if you are given a sedative.

The clouded lens is removed during cataract surgery, and a clear artificial lens is usually implanted. However, in some cases, a cataract can be removed without the use of an artificial lens. Cataract removal surgery methods include:

i) Using an ultrasound probe to break up the lens in preparation for removal. Your surgeon will make a tiny incision in the front of your eye (cornea) and insert a needle-thin probe into the lens substance where the cataract has formed during phacoemulsification.The probe, which transmits ultrasound waves, is then used by your surgeon to break up (emulsify) the cataract and suction out the fragments.

The lens capsule (the very back of your lens) is left intact to serve as a resting place for the artificial lens. At the end of the procedure, stitches may be used to close the tiny incision in your cornea.

ii) Making an incision in the eye and removing the lens whole. Extracapsular cataract extraction, a less common procedure, necessitates a larger incision than phacoemulsification. Through this larger incision, your surgeon will use surgical tools to remove the front capsule of the lens as well as the cloudy lens that is the cause of the cataract. The very back capsule of your lens is left in place to act as a resting place for the artificial lens.

If you have certain eye complications, this procedure may be performed. Stitches are required for the larger incision.

The artificial lens is implanted into the empty lens capsule after the cataract has been removed via phacoemulsification or extracapsular extraction.

Post-Surgery Expectations & Care

Expect your vision to improve within a few days of cataract surgery. As your eye heals and adjusts, your vision may become blurry at first.Because you are looking through a new, clear lens after surgery, colours may appear brighter. Before surgery, a cataract is usually yellow or brown in colour, dulling the appearance of colours. You'll usually see your eye doctor a day or two after your surgery, then again in a week or so to monitor healing.

It is normal to experience itching and mild discomfort for a few days following surgery. Avoid rubbing or squeezing your eyes. On the day of surgery, your doctor may instruct you to wear an eye patch or protective shield.

Your doctor may also advise you to wear an eye patch for a few days after surgery, as well as a protective shield while sleeping during the recovery period. To prevent infection, reduce inflammation, and control eye pressure, your doctor may prescribe eye drops or other medication. These medications are sometimes injected into the eye during surgery.

Most of the discomfort should go away after a few days. Typically, complete healing takes eight weeks. If you experience any of the following symptoms, contact your doctor right away:

  • Loss of vision
  • Pain that continues despite the use of over-the-counter pain relievers
  • Increased redness of the eyes
  • Swelling of the eyelids
  • Flashes of light or the appearance of multiple new spots (floaters) in front of your eye. vi) After cataract surgery, the majority of people require glasses at least some of the time.

When your eyes have healed sufficiently for you to receive a final prescription for eyeglasses, your doctor will notify you. This usually occurs one to three months after surgery. If you have cataracts in both eyes, the second surgery is usually scheduled after the first has healed.
