Question: WHAT ARE THE RISK OF INOCULARY LENSE SURGERY?
Cataract surgery requires diffenent lenses, a. Toric lense, b. Crystalis lense

Answers:

Although complications associated with intraocular lenses and implantation surgery occur in less than 5 percent of cases, some IOL risks do exist.
Beside the general risk of a minor infection that generally can be caught early and managed effectively with antibiotics these are the other possible risks.

Corneal Adema

Corneal edema (swelling) affects most IOL patients to some degree after surgery. Patients who have had previous IOL surgery, endothelial cell loss, or corneal dystrophy are most at risk for experiencing post-operative corneal edema. If the cornea was healthy prior to surgery, the condition should clear up on its own within one or two days. If the swelling persists, your ophthalmologist can provide treatment and medications.

Increased Intraocular Pressure

Intraocular pressure spikes are fairly typical following an IOL procedure. One common cause is temporarily retained viscoelastic. Your ophthalmologist uses this jelly-like substance to facilitate placement and positioning of the IOL. The thick consistency of viscoelastic can reduce outflow of the eye's aqueous fluid, causing a pressure spike that generally peaks about six hours after surgery, then subsides. Intraocular inflammation after an IOL procedure can increase risks of pressure spikes. Your ophthalmologist can provide topical medications that, in most cases, effectively treat the problem. These or similar medications can also treat pressure spikes in IOL patients who have glaucoma.

Leakage

Wound leaks can lead to serious complications if they do not receive prompt, proper treatment because the interior of the eye becomes exposed to infectious agents. Low intraocular pressure following the surgery can be an indicator of a wound leak. If a leak is detected, a bandage contact lens is typically placed over the surgical site. This is usually sufficient to slow the leak adequately to allow natural healing. If the leak persists, the ophthalmologist will use surgical measures to repair the problem.

IOL Decentration

IOL decentration risks arise soon after surgery if the surgeon does not place the lens properly, or if the patient's eye has a weak zonular system for holding the lens in place. Decentration can also occur later if the patient suffers trauma, or internal forces change the dynamics of the eye's lens-containing capsule. Patients with lens decentration experience reduced vision, halos, and/or significant glare. The usual remedy is surgical repositioning of the IOL.

IOL Power Miscalculation

Surgical replacement of intraocular lenses will be necessary if the ophthalmologist misdiagnoses the power of the IOL. Cataract patients who have a history of refractive surgery are at greater risk of IOL power miscalculation.

Retinal Detachment

Retinal detachment caused by IOL surgery is a risk for any patient. A retinal tear that allows ocular fluid to seep behind the retina can occur during IOL surgery. After surgery, the patient experiences flashes and "floaters" in the field of vision. Patients who experience retinal detachment are usually referred to a retinal specialist who may take immediate steps to repair the problem, or, because repair reduces the chances for full visual recovery, may wait to see if the condition improves on its own.
