If the patient chooses to undergo a surgical operation of cataract, he or she may opt on either of the two types of cataract surgery. The eye care specialist can explain the dissimilarities and aid in the determination if which is best suited to the patient.
The two forms of cataract surgery are phacoemulsification shortly called as phaco, and extracapsular surgery. Both are being performed with the aid of microscopy using the microscope for surgery.
In the first form, which is phaco, a tiny cut is done on the cornea’s side, which is the clear, dome-formed surface that coats the front of the eye. The eye care specialist will introduce a small probe into the eye with the help of microscope for surgery. The said gadget releases ultrasound waves that tones down and disintegrate the lens in order that it can be taken away by suction. Nowadays, majority of the cases of cataract surgeries are performed by phacoemulsification with the aid of microscopy using the microscope for surgery. Phacoemulsification is also known as small incision cataract surgery.
In the second form of eye surgery, which is extracapsular surgery, the eye care specialist does a longer cut on the cornea’s side and takes away the blurry core of the lens in a single piece. The remaining lens is getting rid of through suction with the help of microscopy using the microscope for surgery. Frequently, the one being replaced to the natural lens that has been taken away is an artificial lens known as intraocular lens or IOL. The intraocular lens is a clear, plastic lens that does not need any care and ends-up being a fixed part of the patient’s eye as it was placed in the eye with the help of microscopy using the microscope for surgery. The light is focused clearly by the intraocular lens directly onto the retina and enhancing the vision of the patient. The patient will never feel or view the newly attached lens. Nevertheless, not all people who have cataracts can have the intraocular lens. These people are those suffering from other eye illness or have different problems during surgery. It is being recommended that these people will wear soft contact lens or eyeglasses that give great magnification.
Just like the other surgical operations, cataract surgery creates chances of experiencing infection and hemorrhage. Prior to the surgical operation, the eye care specialist may possibly request the patient to stop for the time being the taking of some medications, which amplify the risk of blood loss in the course of surgery. Subsequent to the surgical operation, the patient needs to keep his or her eye clean, wash his or her hands thoroughly before making contact to the eye, and apply the prescribed drugs or medications to lessen the chance of having an infection. Severe infection can end-up in loss of eyesight.
The cataract surgery somewhat elevates the risk of the patient in experiencing retinal separation or detachment. Another eye disorder like high myopia commonly known as nearsightedness may further elevate the person’s chance of retinal separation subsequent to the cataract surgical operation. Abruptly suffering from increased flashes or floaters may indicate retinal detachment. Floaters are small cobwebs or specks that appear to float around in the person’s field of vision. An eye care specialist must immediately be seen in case anyone notices an unexpected rise in the number of floaters or flashes. A retinal detachment is considered as a medical emergency, the patient’s eye need to be checked by an eye specialist at the soonest possible time. There is zero pain in retinal detachment. Permanent vision loss can be avoided if retinal detachment can be treated early. Good vision will be regained if the patient will be treated at the soonest time. Though there are times that vision may be partially lost even if treatment is early.
The removal of cataract via surgical operation is considered as one of the safest and most effectual form of surgery. Individuals who underwent cataract surgery have better vision after it. Prior to the surgery, the patient will have some tests in order to provide the eye surgeon the right information of the condition of the patient. During the surgical operation, drops may be applied to the eye of the patient to dilate the pupil. Other parts of the eye will be washed and cleansed. The surgery may not take more than an hour and is nearly painless because of the anesthesia being applied to numb the nerves of the eye. A medical team will monitor the patient for some signs of infection or bleeding. Most of the patients can go home after cataract surgery on the same day the said surgery is performed.More on this topic
