A cataract is a condition of the retina where the lens clouds and induces a lack of vision. In elderly people cataracts normally occur or after eye damage. The cloudy eye lens has to be replaced by a transparent, artificial lens in order to cure cataracts. Phaco and IOL is a two-part surgical procedure. Second, with the aid of an ultrasonic sample it destroys the cloudy glass. This means that the surgeon places an ultrasound probe in minor incisions in the eye so that he can emulsify the cataract directly. So the intraocular lens (IOL) is inserted in place after the initial eye lens is sucked out.
It is critical that patients avoid taking blood thinning drugs at least two weeks prior to the operation in preparation for phacoemulsification and transplantation of the intraocular lens. You should explore whether you should avoid taking other drugs or supplements with the physicians. Weeks before the surgery, patients should proceed with eye drops. The patient could not eat nor drink anything the night before the surgery.
Patients undergo a local anaesthetic or topical anaesthetic for the management of discomfort and eye movement. Patient treatment since making a slight incision, the surgeon implants the ultrasound sample and extracts the aspirated lens. The IOL is then implanted in a folded or rolled-up shape through the same slight incision. The surgeon assures the right positioning of the new lens. For the incision in the eye no stitches are required as it is self-healing. Overall, it is just 15 minutes per hour for the operation.
Unlikely but also probable are the dangers inherent in this operation. These risks include sudden damage leakage, flashing, swelling, double vision, eyeball infections, retinal separation, glaucoma onset, blindness and secondary characteristics. Eyeball infections may occur, but they are uncommon as post-operative antibiotic drops are typically used. A severe but uncommon side effect is the retinal detachment. The appearance of floating or irregular vision changes can be a symptom of a retinal detachment due to retinal weakness during the procedure. It cannot exist for weeks or months with this side effect. If a secondary cataract forms on the rest of the lens, it may be dissolved by a non-operatory laser treatment.
Most patients have eye sight restored post treatment, and others have the best vision of their life after IOLs have been added. After a cataract corrective operation, most patients will no longer need eye lenses or contact lenses. Increased color and distance sensitivity and regular tasks can be halted in patients because of diminished cataract vision, such as driving, reading or sports.
