Cataract Surgery & Intraocular lenses choice
The lens is a crucial part of the human eye. This is nothing but a space comprising of clear protein and water. It has a vital function in human eyesight. It helps focus light on the retina. This step results in the transmission to the visual centres of the brain.
With growing age, there may be issues with the lens and its organic composition. Older people may complain of the eye lens getting cloudy. This may be due to the change in texture of the protein within the lens. Due to this problem, people tend to view things as blurred. Additionally, there may be an accompanying brownish tint. This condition is known as a cataract.
Timely treatment is necessary for cataract. Otherwise, the person’s eyesight may deteriorate to the point of becoming blind.
Fortunately, this condition is treatable. The patient can undergo vision correction surgery. This procedure comprises of an intraocular lens implant. This is nothing but an artificial replacement for the lens of an eye, which is made of a clear acrylic. IOLs are also referred to as “premium” intraocular lenses. They have the capacity to enhance the vision. They also help the patient to get rid of problems like astigmatism, nearsightedness, farsightedness, reading glasses or computer glasses, and more.
With advancing vision and healthcare technology, there are currently different types of premium IOLs available. The patient will need to check with an ophthalmologist, who will recommend the right type of IOL based on the patient’s specific visual needs, lifestyle, and overall health. This way, the patient gets the most suitable type of premium IOLs to enhance their sight and substitute their eye’s natural lens.
It is recommended to schedule a pre-operative exam and consultation, so that Dr. Mustafa can suggest the most suitable IOL as per your distinct requirement.
Types of Cataract Intraocular Lenses: (IOLs)
Patients can check out the different types of IOL’s specifically for treating cataract.
1 – Toric IOLs:
These lenses specialize in rectifying astigmatism. They are equally effective for farsightedness. Patients with nearsightedness too have reported good vision improvement with Toric IOLs. These lenses are available in various degree of powers. They offer one more advantage during the operation. The surgeon can make use of the peripheral alignment markings on the lens to re-calibrate the IOL’s alignment so that it can perfectly fit the eye.
It is common for the surgeon to mark distinct coordinates in the patients cornea prior to the procedure. This is temporary in nature. It is needed so that the IOL can align perfectly with the front of the eye by continuously re-calibrating the IOL markings with that of the cornea. This ensures proper rectification of the issues of astigmatism.
2 – Extended Depth of Focus or Multifocal IOLs:
In a typical scenario, the cataract operation requires the patient to wear glasses after the procedure for near. But with the multifocal IOLs, the patient can get rid of glasses after the cataract operation for majority of visual tasks. These types of IOLs are known for rectification of presbyopia. As a result, the patient need not put on glasses for reading or vision correction. Due to its unique characteristic, the lenses come with added magnification feature. Hence patients can see things clearly from a distance or from close by. This eliminates the need for glasses or contact lenses for majority of tasks.
3 – Monovision:
With this type of IOL, the surgeon aims to rectify the refractive error of one eye and purposely brings about nearsightedness in the other eye. The degree of nearsightedness is extremely miniscule. As a result, the completely cured eye can see objects at a distance clearly. In contrast, and mildly nearsighted eye gets to see up close objects without using glasses. Over a period of time, the patient adapts and uses the dominant eye to view distant objects and the non-dominant eye to view near items.
