Introduction
Cataract, a common eye disorder can affect your daily routine work. The blurred vision makes daily activities a challenging task. With technological advancement and new developments in medical science, it has become possible to get cataract treatment easily. These days different types of lenses are available that can make your life easy. In this article, we discuss the different types of cataract lenses and how to select the best for your eye.
What is cataract surgery?
In cataract, our lens gets opaque making our vision unclear and blurred. To overcome the situation the original lens of the eye is replaced by an artificial intraocular lens (IOL) that helps us see clearly. IOL comes in different types, each having its unique benefits.
Types of IOLs
Standard IOL
These are mono-focal lenses that focus on distance vision only. The lens provides crystal clear vision for distance, just as in virgin eyes. However, for near-vision activities such as reading the newspaper, or working on a computer, laptop, or mobile patients rely on glasses or contact lenses.
Premium IOL
Premium IOLs offers a wide range of benefits and are classified further into:
- Toric lens: These lenses address astigmatism concerns caused by a different curvature of the cornea or lens of your eye along with cataract. One of the lens surfaces resembles a “cap” from a torus, while the other usually appears spherical.
- Accommodation lens: The lens is termed so as it has flexible “arms” known as haptic. These haptics use eye muscle movements to shift attention from far to near. Thus, it offers multiple focal benefits to the cataract patient.
- Light Adjustable Lens (LAL): They are the only intraocular lens (IOL) that allows customization of your eyesight following cataract surgery. Adjustability elevates cataract surgery by providing a lens tailored specifically to your eyes.
- Multifocal contact lens: These lenses combine multiple prescriptions in one lens. There are usually three prescriptions, that is near, intermediate, and distant objects. The lens allows all the prescriptions and eases the patient’s life. Furthermore, this setup assists persons with presbyopia in correcting age-related vision issues in which the eye cannot focus on nearby objects.
- Expanded Depth of Focus IOLs (EDOF): These lenses can focus at intermediate and distance and not near vision. EDOF IOLs are an advanced form of multifocal IOLs as they give a continuous range of focus, preventing picture overlap and removing the halo effect.
What are the Latest Treatments for Cataract?
Some of the latest treatments for cataract surgery are as follows:
- Phacoemulsification: It is the most common treatment for cataract removal. It includes inserting an ultrasonic instrument into the eye through a tiny incision. The vibrations break up the eye’s lens, allowing it to be removed via suction. An artificial lens is then placed in the eye.
- Robotic Cataract Surgery: It is a faster and hassle-free technology for cataract treatment. The surgical steps are assisted by femtosecond laser incisions which are precise and reproducible. It is highly accurate and gives excellent outcomes, free from human error.
