Cataract Eye Surgery

What is Cataract?

A cataract is a commonly occurring age-related disorder of the eye which entails clouding of the natural transparent lens. It can neither be cured with medications nor corrected with glasses. Patients with cataracts need to undergo surgery for cataract removal.

The phenomenon of cataract occurs when the protein clumps start accumulating in the lens. This forms a white opaque film in the eye’s natural lens that prevents light from passing through it to reach the retina.

Yellow or brown discolouration often occurs as the cataract gets denser. As you age, the lens proteins start degrading, and the cloudy area gets denser, resulting in complete loss of vision.

Reasons for the development of cataract

Ageing: People older than 60 years of age are at the risk of getting cataracts.

Exposure: Overexposure to UV rays can negatively affect the eyes and cause cataracts.

Drug-induced: One can get cataracts due to prolonged usage of steroids and other prescription drugs.

Diabetes: People with diseases like diabetes are more likely to develop a cataract.

Injury-induced: An injury to the eye can cause cataract or even complete loss of vision.

Cataract Symptoms

Hazy, fuzzy and blurred vision

Double vision

Increased sensitivity to light

Poor night vision

Rapid need to change eyeglass prescription in the early stage

Cataract Treatment: When To Go For Cataract Eye Surgery

A team of medical professionals at our centre performs various tests and recommends necessary treatment to the patient. If the cataract is harmless, it can be left untouched. As soon as it starts blocking vision and performing routine tasks becomes a hassle, one should consider testing and surgical solutions for cataract eye surgery.

The different types of tests we do for
cataract treatment are

Tests Function
Biometry/ Intraocular Lens (IOL) Workup To check the IOL power required in the eyes.
Specular Microscopy It is a noninvasive photographic technique that checks the status of the cornea and any corneal diseases.
OCT Test It is a noninvasive imaging technique that monitors the status of the retina and its distinctive layers.
B Scan/ Ultrasound B Scan is used when the cataract is very dense or mature and hence is not allowing visualization of retina. With this ultrasound system any gross pathologies behind the opaque lenses are attempted to be ruled out.
Pentacam Test It is a scanner that shows images of the anterior segment of the eye and provides data that helps surgeons plan the cataract treatment, especially prior to implantation of premium intraocular lenses or test irregularities in the cornea.

What Happens During Cataract Eye Surgery?

During cataract eye surgery, surgeons remove the lens, which has become cloudy and
replaces it with an artificial and clear intraocular lens (IOL).

Your ophthalmologist may instruct you not to eat any solid meal up to six hours before the cataract surgery. You could also be asked to stop any medication to avoid bleeding during the surgery. Cataract surgery is done on a day care basis.

Your eyes will be numbed with eye drops or injection. You will remain conscious during the surgery, but will not feel any pain.

In robotic cataract surgery or Femto cataract, a camera/ultrasound/scanning device is used to map the patient’s eye and gather information about the lens. This data is then sent to a computer which programs the laser to perform the incisions required in the surgery with robotic precision.

The incision made during SMILE surgery is only 2mm wide, far less invasive than the 20mm one made in LASIK or the 8mm one done during PRK procedures.

In a maximum number of cases, no stitch is required to close the tiny incision and you are allowed to go home post-surgery, cataract surgery being a daycare procedure. If it is required to cover that tiny incision, surgeons may stitch to close that area. A patch or protective glasses will be placed over your eye for quick recovery. You will be asked to rest for thirty minutes before leaving for home.

What happens after cataract surgery?

Right after the cataract surgery is done, your surgeon will do a post-op evaluation and will give you a few recovery instructions.

Please arrange a driver to go back home as driving is not advisable right after the surgery is done.

You will be administered with medicated eye drops, and you will be prescribed to use them for a couple of weeks after the surgery.

You will be advised not to get involved in physically straining activities like heavy weight lifting, getting indulged in intensive exercises, etc.

You will also be advised to protect your eyes from infection-causing elements and dust. Keep your eyes closed while taking a shower. Do not rush to go to the swimming pool, hot tubs at least for three weeks after cataract surgery.

There are numerous types of intraocular lens
(IOL) options that we use to replace the original

Intraocular lenses measurements are different in different individuals and many times in two
eyes of the same person. The measurements depend on the length of the eyeball and shape
of the front glass of the eyeball called cornea in most circumstances.

Monofocal Lenses

These are the most commonly used intraocular lenses. Monofocal lenses have the ability to focus light rays for either distance or reading as per the patient’s requirement. Most patients prefer correction for distance, hence after getting a monofocal lens, a reading correction is often required

Toric Lenses

Patients who have varying light bending abilities in different meridians on the cornea/ front glass-like dome of the eye are said to have astigmatism. These patients require special intraocular lenses that account for their astigmatism. Such lenses are called toric lenses. They can be monofocal or multifocal in nature.

Aspheric Lenses:

These lenses offer contrast sensitivity and good vision, especially at night.

Multifocal Lenses

Multifocal lenses ensure good quality vision and eliminate the need for corrective glasses. Multifocal lenses have concentric rings that help patients see for most distances with minimal requirements of glasses. However, your suitability for these lenses can only be decided upon by your surgeon after a thorough examination.

Newer Multifocal IOL

Most of the issues that were present in the multifocal lens are resolved in this lens. Thus, halos and glares are also reduced.

Trifocal lenses

Trifocal lenses offer clear vision at an intermediate level (generally an arms length). These lenses correct both near and far vision also. The most significant advantage of trifocal lenses is they allow the person to switch effortlessly between near, far, and the in-between distances.

Extended Depth of Focus IOLs

It is a new technology that helps in the treatment of presbyopia. EDOF lenses create a single elongated focal point to enhance the depth of focus. It enhances the sharpness of vision at near, far and intermediate distances.

How to choose an IOL?

You can choose from a range of IOLs, depending upon your specific needs. If you do not mind wearing spectacles after cataract treatment, then a monofocal lens implant can be used. Generally, people require glasses only for reading purposes after the surgery.

If you do not want to wear spectacles after cataract surgery, then your surgeon will correct presbyopia by adjusting the power of one of your monofocal intraocular lenses. This will give you monovision correction.

Through advanced presbyopia-correcting IOLs, you can also choose to improve your reading vision without compromising on distance vision. You can select presbyopia-correcting IOLs which includes accommodating IOLs and multifocal IOLs for a greater range of vision.

Centre for Sight offers several surgical options depending upon the severity of the cataract, its cause, and current condition of the patient’s eyes. The surgery best suited to the case is suggested after thorough testing.

What are the common symptoms of a cataract?

Cataracts grow gradually with the slow blurring of vision that is not correctable by glasses. Some people get their vision quickly deteriorated, with difficulty in nighttime driving, glares, halos, and overall foggy vision.

Do cataracts develop due to getting old?

Cataracts commonly occur in adult life. These are age-induced cataracts and may develop after 40 years of age. But not all people develop a cataract in old age and not all who develop it require treatment.

Does cataract happen in children?

Cataract can happen in children. Any white reflex observed in children should be taken very seriously. Visit pediatric ophthalmologist at Centre for Sight for prompt diagnosis and management.

If I have a cataract in both eyes, can they be treated at the same time?

Cataract generally develops in one eye faster than the other, so it is advisable to operate the one in worse condition first. But it is possible in exceptional situations to operate on both at the same time at Centre for Sight after understanding the pros and cons of the process.

Does a previously done laser operation matter in cataract treatment?

Since Lasik changes the shape of your cornea, accurate knowledge of measurements is essential for correct calculation of intraocular lenses, and it is imperative to inform your surgeon.

What are the risks or complications involved with cataract eye surgery

Though the risks involved with cataract eye surgery are quite uncommon but may include few complications can be inflammation, bleeding, swelling, drooping eyelid, glaucoma, loss of vision, dislocation of an artificial lens, secondary cataract, infection, retinal detachment, etc.

Will I be awake during the cataract surgery?

Yes, a person remains awake during the cataract surgery.

How long does the cataract surgery take?

Cataract surgery typically lasts for 15-20 minutes.

I cant see anything clearly after the operation. What should I do?

Give your eyes sometime before it gets back to normal vision. Vision may be impaired for the first few days of cataract surgery.

What is Posterior capsule opacification?

Posterior capsule opacification is one of the common sequlae of cataract surgery. It makes your vision blurry. It is often known as a secondary cataract, which depicts opacification of the bag in which the artificial lens was initially placed. This is easily treatable as an office procedure in a painless manner with the help of YAG lasers.

Can an artificial lens become cloudy later?

No. It doesnt happen. However, overtime posterior capsule opacification may develop, which is removed using a laser on an outpatient basis.

How long does it take to get back to work post-cataract surgery?

Most patients can get back to work However, overtime posterior However, a weak-long rest is ideal. You would need to maintain precautions like no splashing of water in your eyes for up to three weeks and keep putting medications as recommended by your surgeon for six weeks or more as required.
