Medical Video: Cataract surgery: my thoughts after the operation
Cataract surgery is a simple surgical procedure to remove lens fog in the eyes that have cataracts and replace them with clear artificial eye lenses. The replacement of the implant's eye lens aims to improve eye acuity. The following types of implant lenses you need to know, before entering the operating room.
Wide selection of implant eye lenses used in cataract surgery
The implant eyepiece used is generally made of silicon or acrylic which is then coated with special material to counteract UV light. There are 4 types of implant lenses that can be used according to the needs of each patient. Here's the explanation:
1. Monofocal lens
Monofocal lenses are the most common and traditional types of implant lenses. This lens has only one focus - close, medium and far focus depending on the patient's wishes. Generally this type of lens is chosen to help focus long distances. Close-range focus, such as when reading, will be helped by using reading glasses.
This type of lens is also the best type of lens when users often drive at night because it has a smaller glare effect than other types of lenses.
2. Multifocal lenses
This lens has two focal points, namely close range focus and long distance focus. This lens is designed so that the brain can choose the focus point that is suitable for the desired vision. Multifocal lenses have a much more expensive price than monofocal.
3. Accommodating lenses
The need to get the best vision in all situations leads to the creation of accommodative lenses. This lens is specifically made to be able to relate to the ciliary muscle (the eye muscle that regulates the ability to bulge and flatten the eye lens) so that the lens can move forward or backward to adjust focus based on the location of the object.
Relaxation of the ciliary muscle will cause the lens to move backwards and improve long-distance vision. Conversely, the contraction of the ciliary muscle will cause the lens to move forward and help for close vision.
4. Torik lens
Unlike other types of lenses that help to overcome the minus and pluses in the eye, this type of lens is intended to deal with cylindrical eyes (astigmatism). The use of torik lenses provides the best results in dealing with cylindrical eyes compared to various other techniques, such as reducing the area of surgery or the limbal relaxing incision method.
What needs to be considered before choosing an implant lens
In the end, the choice of implant lenses depends back on the initial conditions of eye health, needs, and also the costs that you have.
It cannot be denied that costs must be one of the considerations in the selection of lenses because the more sophisticated the type of implant lens to be used, the greater the cost to be incurred.
These things should be discussed further together with an ophthalmologist who will carry out your surgery to get the best final results.
