Cataract Surgery

Causes of Cataracts

Cataracts can develop due to various reasons, and their treatment is essential for maintaining eye health. Cataract surgery restores vision by removing the cloudy lens and replacing it with a clear artificial lens. Some types of cataracts may require specialized treatment and equipment. Common causes include:

• ⬩Aging
• ⬩Excessive exposure to sunlight
• ⬩Exposure to toxic chemicals
• ⬩Metabolic changes in the body
• ⬩Injury or trauma

Cataracts are more common in individuals aged 52-64, but they can also occur at younger ages or be present at birth.

How is Cataract Surgery Performed?

Cataract surgery is a relatively simple procedure performed in an operating room under sterile conditions, often with the aid of an operating microscope. The duration of the surgery can vary depending on the hardness of the cataract and the type of lens used, typically ranging from 10 to 30 minutes. Factors that might extend this duration include the specific needs of the patient and any additional surgical tools required.

The type of anesthesia used is determined by the surgeon. Local anesthesia with sedation is common, allowing the patient to remain comfortable without feeling pain, although they may sense slight pressure. The patient's vital signs are monitored throughout the surgery, ensuring safety.

Delaying surgery can lead to the cataract becoming harder, increasing the risk of complications. Thus, timely intervention is essential for successful treatment.

Phacoemulsification for Cataract Treatment

Phacoemulsification is one of the most widely used methods for cataract treatment. It involves making small incisions and using ultrasonic waves to break up the cloudy lens, which is then removed and replaced with a clear artificial lens. The procedure is typically performed under topical anesthesia, which numbs the eye with drops, and no stitches are required. The success of the surgery heavily depends on the surgeon's experience and the quality of the surgical equipment used.

Premium Smart Trifocal Lenses

Premium smart trifocal lenses help patients see clearly at near, intermediate, and far distances without glasses. Unlike single-focus lenses, trifocal lenses provide three focal points, reducing the need for glasses post-surgery. This allows patients to engage in various activities without the dependence on corrective eyewear.

Premium Smart Trifocal Toric Lenses

Premium smart trifocal toric lenses are widely used in cataract treatment. They address astigmatism in addition to providing clear vision at multiple distances. Age-related changes in the protein structure of the eye's lens can lead to clouding and blurred vision, which these advanced lenses can effectively correct.

Multifocal Lenses

Multifocal lenses address multiple vision issues simultaneously. Patients who struggle with both near and far vision can benefit from these lenses, eliminating the need for multiple pairs of glasses. These lenses are also used post-cataract surgery to restore clear vision at various distances.

Monofocal Lenses

Monofocal lenses are used during cataract surgery to replace the clouded natural lens. They provide clear vision at one specific distance, typically far. Factors such as sun exposure, trauma, aging, and exposure to certain chemicals can lead to the development of cataracts, which are best treated surgically.

Monofocal Toric Lenses

Monofocal toric lenses are designed to correct astigmatism in addition to replacing the clouded lens during cataract surgery. These lenses provide clear vision at one distance and correct the irregular curvature of the cornea or lens that causes astigmatism.
