No CommentsThe latest types of lenses that can be implanted after removing the cataract
With the question of Dr. Hantira, an honorary assistant professor at the ophthalmology department, Umm Al-Qura University, Saudi Arabia
Explain to us the events of the types of lenses that can be implanted after removing the cataract, including:
• The lenses made of hydrophobic IOL, which are characterized by reducing the incidence of fractures and opacities on the back capsule of the eye lens, which reduces the need for a yag laser after the operation.
• Monofocal lenses (Monofocal IOL) are used to correct nearsightedness and farsightedness to dispense with distance glasses.
• Aspheric IOL significantly improves night vision clarity and color contrast.
• Astigmatism correction lenses (Toric IOL) for patients with corneal surface irregularities.
• Multifocal lenses (Multifocal IOL), which allow the patient to have the clarity of far and near vision at the same time, thus the patient does not need glasses for reading.
Dr. Hanatera will assist you in choosing the right type of lens that is appropriate for your condition based on a careful examination of the eye to measure its dimensions, the degree of curvature of the cornea and the amount of alignment.
What are the implanted lenses made after removing the white water?
Lenses are implanted with flexible, ultra-transparent polymers. The diameter of these artificial lenses ranges from six to seven millimeters, and their thickness ranges between half and one millimeter, and their weight is less than one gram. During surgery, the lens is folded and injected into the eye, where it relaxes automatically. Flexible hooks on the edge of the artificial lens ensure that they remain in place.
Does white water return after removing it?
This cannot happen at all, but the lens capsule can darken in a small percentage of patients and in this case it is treated with a non-surgical laser in less than one minute outside the operating room.
How long does the cataract operation take with a phaco or phtolizer?
The process takes about 5 minutes
What type of anesthesia is used during the operation?
Due to the ease and speed of the operation, the operation is performed under the influence of a local anesthetic drop that prevents pain and prevents eye movement.
