Cataract surgery Sydney, being an outpatient procedure, has many benefits and risks to correcting double vision. The eye pressure is numbed with anesthesia while making a tiny incision during the procedure. Also, the eye surgeon inserts an intraocular lens (IOL) into the eye to replace the natural lens. This occurs after removing the cloudy lens. The new artificial lens now serves as a clear lens for normal vision. 

To prevent infection after the procedure, patients must keep a follow-up appointment with the doctor’s office. At the same time, the eye heals through a natural process in about a month.

What is Cataract Surgery?

Cataracts, cloudy spots that form in the eye’s lens can be surgically removed through cataract surgery. Cataracts cause vision problems such as blurriness, sensitivity to glare, and trouble seeing in the dark. During cataract surgery, the cloudy lens is removed and replaced with a clear artificial lens called an IOL.

The procedure typically requires local anesthesia, so the patient will be awake but have a numbed eye. Surgeons can break up cloudy lenses using ultrasound or other techniques through tiny incisions in the eye. The IOL is then positioned in the correct location within the eye and inserted through the same incision.

Cataract surgery has a high success rate in restoring vision. It is generally regarded as a safe and effective procedure. Most patients’ vision improves noticeably after surgery and is fully functional in weeks. It is uncommon that additional procedures would be required to fix any lingering vision issues.

What is an intraocular lens?

Cataract surgery replaces the eye’s natural lens with an artificial lens. This lens is called an intraocular lens (IOL). Moreover, the IOL replaces the eye’s natural lens and allows clear vision.

The wide varieties of IOLs on the market today have their advantages. Some IOLs are monofocal, optimized for clear vision only at one distance. Other IOLs are multifocal or accommodating. It means they are made to give the patient clear vision at various distances. Also, it removes the need for glasses or contact lenses.

IOLs are typically made of silicone or acrylic materials. They are tiny and flexible, allowing them to be folded and inserted through a small incision in the eye. In addition, the IOLs are long-lasting and won’t ever need to be removed or replaced.

IOLs can significantly enhance a patient’s vision and overall quality of life when used with cataract surgery. Your eye doctor can advise you on the type of IOL that will work best for your eyes.

Different kinds of Intraocular Lenses (IOL)

IOLs are a unique lens of the eye to replace the natural eye lens during cataract surgery. These lenses also come in different focusing powers. Depending on your artificial lens, you may not need your glasses before the cataract surgery. Remember, the IOL requires ultrasound waves in the hands of a cataract surgeon. The procedure known as phacoemulsification cataract surgery corrects a cloudy natural lens capsule.

Below are the different types of IOLs for cataract surgery

Monofocal IOLs

Monofocal intraocular lenses (IOLs) are designed to correct vision for a specific distance, unfortunately, that leaves patients dependent on corrective lenses like glasses or contacts for distance vision.

Multifocal IOLs

Multifocal IOLs allow patients to see clearly at various distances. In Multifocal IOL, patients do not need eyeglasses or contact lenses.

Accommodating IOLs

Accommodating intraocular lenses (IOLs) allow patients to see clearly at various distances. It is without the use of corrective glasses or contact lenses. Instead, the process bends or changes the shape in response to the eye’s natural movements.

Toric IOLs

Toric intraocular lenses (IOLs) are created specifically to treat vision impairment. The eye trouble could be caused by astigmatism, which is caused by an irregular corneal shape. Another one can be macular degeneration, which requires a new lens capsule. 

Extended Depth of Focus (EDOF) IOLs

IOLs with an extended depth of focus (EDOF) lessen the patient’s reliance on corrective eyewear. In addition, it allows a blur-free viewing at distances ranging from infinity to infinity and a half.

Phakic IOLs

Phakic intraocular lenses (IOLs) correct refractive errors. It could be myopia (nearsightedness) or hyperopia (farsightedness). They are implanted in front of the eye’s natural lens rather than replacing it. Another method is the YAG laser capsulotomy to correct another eye infection.

Who needs cataract surgery?

Cataracts are cloudy spots that form in the eye’s lens, and in most cases, surgery is recommended for those with them. Cataracts can lead to blurred vision or trouble seeing at night.
