What is Cataract surgery ?

Cataract surgery in Iran Eye cataract refers to the medical condition during which a cloud forms in eye lenses and cause blurry vision by glancing the light. In severe cases, eye Cataract can make daily life activities impossible, and usually, in this situation, doctors recommend cataract surgery. Cataract surgery is a procedure during which eye cataract is removed and replaced with an artificial lens. In most cases, a prolonged waiting period before the operation is harmless for eyes. This provides a gap for patients to consider their other probably treating options.

A Cataract is a layer inside the lens of the eye that reduces vision. This problem cannot be modified by non- surgery options such as glasses, lenses or Lasik. Modern cataract surgery can usually restore lost vision and can often reduce the dependence on glasses. Most cataracts are prevalent at an early age, and this is common in Iran. Luckily, modern cataract surgery is one of the best methods of operation nowadays

Cataract surgery

Cataract is referred to as the opaque lens that is usually transparent. For people with cataracts, looking through dark lenses is a bit like looking through foggy glasses. Having cataracts makes reading, driving (especially at night) and seeing people’s faces difficult. Cataracts initially do not greatly affect vision. In these conditions, using glasses and a brighter environment can help prevent blurred vision, but the disease progresses slowly and ultimately affects vision. In this case, cataract surgery may be required. Fortunately in general, cataract surgery is an effective and safe method.

In cataract surgery, the lens extracts from the eye through the intra-capsular-lens method with the surrounding capsule, leaving no room for intraocular lens placement. This method is now almost abandoned and is only used in certain cases, such as when the lens is half-blown and the lens capsule cannot hold. In extra capsular cataract surgery; after opening the anterior portion of the lens capsule, its contents are removed and the lens capsule chamber can then be used as an intraocular lens placement. This cataract surgery procedure is performed in two forms:

1 – with large incision
2 – with small incision;

Cataract surgery is performed with a large incision extra capsular; the cornea attaches to the sclera (limbus) about 9 to 11 mm in length, and after opening the anterior capsule, the lens core is removed and after washing the remaining lens material, the lens is inserted into the eye and the incision is closed with 6 to 9 sutures. About two to three months later the sutures are removed. So it takes about two to three months for the vision to reach a relatively normal level. Therefore, the main drawback of this approach is its long recovery time after cataract surgery. In the 2^nd cataract surgery method, the cataract extraction is performed using a small incision, about 3 mm in diameter, to remove the contents of the lens.

How cataract surgery is done?

Cataract surgery is uncomplicated and usually takes about 15 minutes. But you are expected to stay in the surgical center for about 90 minutes or more, as it is an extra time to prepare you for operation (pupil flexibility, preoperative drug control) and for short-term evaluation after the operation. You will also be given instructions on cataract surgery before leaving the clinic.

An eye protection shield should also be used while sleeping or waking up about a week after the cataract surgery. To protect the eye from sunlight and other lights, two sunglasses after the operation should be used for complete recovery. Many centers also recommend that if anesthetic is prescribed, one person should be present at the clinic with the patient. This will ensure that you are fully prepared for the cataract operation. As your eye heals, you may experience redness and blurred vision in the first few days or even weeks after the operation.

What you should avoid after cataract surgery?

During the first few weeks of recovery after the cataract surgery, it is important to avoid:

Intense activity and heavy lifting (over 25 pounds).
Bending, exercise, and similar activities that may affect your eyes during recovery.
Water should not contact the eye as it can cause infection.
Keep your eyes closed while showering or bathing.
Also, avoid hot baths or baths for at least two weeks.
Any activity that exposes your eyes to dust, pollution or other infectious contaminants.

After the cataract operation, you will need a companion and will not drive until the day your doctor checks your eye, then you can drive. Some types of eye drops will be prescribed for several weeks after cataract operation. Depending on your specific needs and surgical outcomes, the surgeon may recommend other guidelines and recommendations for recovery after cataract surgery. If you have questions at any time after the operation, you can consult your doctor. If you need cataract surgery in both eyes, the surgeon will usually tell you to wait one to three weeks, so the eye operation will be sufficiently healed before the next eye operation.

What are the costs of cataract surgery?

The cost of cataract surgery depends on different factors, such as your doctor, type of procedure as well as the type of intraocular lens he/she is going to use for your eyes. Fortunately, most of the medical insurance companies support cataract surgery. However, in most cases, the expenses of lenses should be covered by patients themselves. This is due to a variety of types and prices of lenses.

The cost of cataract surgery for people who are not covered by health insurance is slightly higher than for others. The actual amount paid for cataract operation in people who are not covered depends on various factors, including the type of IOL that is placed in the eye, the type of technology used during operation, and the skill and experience of the surgeon. Fortunately, most cataract surgeries are fully or partially covered by health insurance. If you have chosen standard monofocal IOL cataract operation, this procedure may be performed at a low cost (excluding exemptions and joint insurance payments). But if you have selected cataract surgery with a multi-center IOL for correction of astigmatism or ophthalmology by the IOL, you are likely to pay extra for these advanced techniques and lenses.

Causes of Cataract

Most cataracts develop during aging or damage to the lens tissue of the eye. In some cases, it is due to inheriting genetic disorders that can lead to health problems and an increased risk of cataract. As the age increases, the flexibility and transparency of the eye lenses become less and thicker. The changes that occur with age in the lenses lead to the darkening of parts of the lens that become more severe as the disease progresses. Cataract can occur in one eye or in both eyes.

Cataract surgery benefits

Surgery is the only effective way to treat cataracts. When cataracts affect a patient’s quality of life or impair the patient’s ability to perform daily activities such as reading and driving, most physicians recommend performing cataract surgery. Cataract surgery involves replacing dark-eyed lenses with implant and plastic lenses. Replaced lenses, like eye lenses, become a part of the eye. In some people, other eye problems prevent the replacement of the lens. In such cases, vision can be improved by using glasses or medical lenses. Each eye surgery is performed separately and usually within a few weeks. This type of surgery is usually included in outpatient surgeries, meaning that the patient will not need to be hospitalized after cataract surgery. During cataract surgery, the surgeon uses local anesthesia around the eye. This is generally safe, but the patient may have problems such as infection and bleeding. It also increases the risk of retinal detachment.

Frequently asked questions about Cataract surgery

Is cataract eye disorder common only among older adults?

Yes, the chances of having cataract surgery are higher among patients over age 50. Nearly all people above the age of 75 will need to do this surgery. However, congenital cataracts are a rare but possible case among infants. Congenital cataracts are more frequent among infants of mothers who had chickenpox or other infectious diseases during their pregnancy. Congenital cataracts can also be inherited.

How does a cataract get removed?

To restore the patient’s vision, the damaged cataract will be removed and replaced with a clear implant called an intraocular lens. During the cataract surgery, with a scalpel or a laser, a small incision will be made in the front eye surface. Lasers can break the eye lens into small pieces to ease the process of its removal. Usually, eyes will heal quickly after surgery, and no need for stitches is needed. Nowadays, computer-controlled lasers can complete many steps of cataract surgery. Thus, human-based risks of this surgery have decreased significantly.

How long would the surgery take?

The procedure usually takes place between 15 to 30 minutes. However, complications during the surgery, along with the preparation steps, may prolong this duration to 2-3 hours.

What are the essential pre-operation steps?

Usually, before the surgery, patients are instructed not to drink or eat anything for 12 hours. Patients also need to stop taking any other medications temporarily before the surgery, as it might increase the risk of bleeding during the operation. In this regard, you need to well inform your doctor about your medical history and medicines you take before the start of surgery.

What are the possible side effects of eye cataract surgery?

Similar to other surgeries, post-operation complications after cataract surgery are possible. These complications might be as follow: pain, swelling, infection, and bleeding. Fortunately, only a few people may experience these complications after surgery. Following instructions suggested by your doctor after eye cataract surgery can reduce the risk of post-operation risks drastically. Report any unusual symptoms to your doctor immidietly to manage further risks after the surgery.
