Pseudophakia (pseudophakia) and intraocular lenses

Surgery is the main treatment for cataracts. Before surgery, your doctor will measure the size and shape of your eye to choose the correct lens. You will receive drops to dilate. The area around the eye will be cleaned and you will also be given medication to anesthetize your eye so that you do not feel any pain. The doctor will remove the affected lens by one of these techniques: - Facoemulsification: The doctor makes a small cut at the front of the eye. A probe that transmits the ultrasound waves is inserted into the cut to break down the cataract.

The parts of the old lens are then aspirated. - Laser: The doctor uses a laser to make a small cut in the eye and to break the cataract to be removed. - Incision for extra-capsular cataract: The doctor makes a larger cut at the front of the eye and removes the entire cataract affected by the cataract. Once the old lens is removed, the doctor will implant the new lens into the space it leaves behind. The incision is then closed.

A patch or dressing will be applied over the eye to protect it while it heals. You can go home the same day of surgery but plan to return because you will need someone to lead you. Possible side effects of pseudophakia include: - too much or too little correction of vision, - the lens is placed in the wrong position, - the lens is removed and blurred vision, - fluid accumulation and retinal inflammation, called Irvine-Gass syndrome. The risks of cataract surgery include: - infection - bleeding - swelling and - loss of vision - double vision - increased eye pressure that could lead to glaucoma -. Cataract surgery with pseudophakic IOL may improve vision in approximately 90% of people who have opted for this procedure.

Most implanted IOLs are monofocal. They can only help at a distance - close or far. However, multifocal lenses are also available for certain people. After surgery, you will most likely have to wear for reading or driving, depending on the type of IOL you receive. .
