Agree toTerms and ConditionsExtracapsular cataract extraction surgery is a surgical procedure that is used to remove a cataract from the eye. When a person has a cataract, there is clouding of the lens in the eye. This can cause vision problems. This surgery is performed when the cataract has become too dense to be removed through a small incision in the eye. During the surgery, the surgeon will make a large incision in the eye and remove the eye lens. The lens is then replaced with an artificial lens to restore clear vision.
Manual extracapsular cataract extraction is an old and most commonly used method of removing a cataract. During this procedure, the surgeon will make a large incision in the eye and remove the lens of the eye manually. Once the lens is taken out, an artificial lens is implanted to restore clear vision. This procedure is performed under local anesthesia and usually takes about 30 minutes to an hour to complete. The recovery time for this surgery is typically longer than other types of cataract surgeries.
Phacoemulsification extracapsular cataract extraction is a relatively newer surgical technique that makes use of ultrasound energy to break up the cataract. During the procedure, the surgeon will make a small cut in the eye and insert a small probe that emits ultrasound waves. These waves break up the cataract into small pieces, which are then removed from the eye. This procedure is less invasive than manual extracapsular cataract extraction and has a shorter recovery time. The surgery is performed under local anesthesia and usually takes about 20 to 30 minutes to complete. The smaller incision used in this procedure also reduces the chances of developing complications and allows for faster healing.
Extracapsular cataract extraction surgery is an effective way to restore vision by removing a cataract. There are two types of extracapsular cataract extraction procedures: manual extracapsular cataract extraction and phacoemulsification extracapsular cataract extraction. Each procedure has its own advantages and disadvantages. The best treatment option for a patient depends on their individual needs and circumstances.
Extracapsular cataract extraction surgery is recommended for individuals who have a mature cataract and have difficulty seeing or performing their daily activities. Cataracts can also cause other vision problems such as glare, halos, double vision, and color distortion. Other factors that may necessitate cataract surgery include:
Significant vision loss
Difficulty seeing at night or in low light conditions
Blurred or cloudy vision which cannot be corrected using glasses or contact lenses
Difficulty reading or recognizing people's faces
Difficulty performing daily activities such as driving, cooking, and cleaning
Before undergoing the surgery, consult with an ophthalmologist to determine the best course of action. During the consultation, the ophthalmologist will see how severe the cataract is, review medical history, and do a comprehensive eye exam. The ophthalmologist will also discuss the possible risks and benefits of the surgery, as well as any special instructions or precautions that need to be taken before and after the surgery.
Patients may need to undergo several preoperative tests to ensure they are suitable for surgery. These tests may include blood tests, electrocardiogram, and other diagnostic tests. Patients should also inform their eye doctor of any medications they are taking, including prescription and over-the-counter drugs.
Patients must follow the preoperative instructions given by their ophthalmologist closely. These instructions may include preoperative fasting, avoiding some medicines, and using the prescribed eye drops.
Patients will need someone to safely help them reach home postoperatively, as they will not be able to drive themselves. Patients should arrange for transportation in advance and have someone stay with them for the first 24 hours after the surgery.
Patients should prepare for the recovery period by arranging for assistance for routine activities such as cooking, cleaning, and running errands. Strenuous activities and heavy lifting should be avoided for several weeks after the surgery. Extracapsular cataract extraction surgery is safe and effective and can improve vision and quality of life. By following these steps, patients can ensure a successful surgery and recovery.
Before the surgery, the patient will speak to the doctor to make sure that this is the correct treatment option for them. The eye doctor will evaluate the patient's eye and medical history, conduct an eye exam, and discuss the risks and advantages of this operation.
The patient may undergo several tests to evaluate the health of their eyes and determine the appropriate surgical technique. These tests may include visual acuity testing, corneal topography, and measurement of the eye's axial length.
The patient will receive instructions from the eye doctor on how to prepare for the surgery. These may include instructions on fasting, the use of medications, and avoiding certain activities before the surgery.
The ophthalmologist makes a small incision in the eye's cornea or sclera.
The ophthalmologist creates an opening in the lens capsule, which is the thin membrane that surrounds the cataract.
The ophthalmologist removes the cloudy lens of the eye through the incision. This may be done using a specialized instrument, such as a phacoemulsification probe, which uses ultrasonic vibrations to break up the lens into small pieces that can be removed more easily.
The ophthalmologist inserts a clear artificial lens into the eye to replace the cloudy lens that was removed. This may be done through the same incision used for the extraction or through a separate incision.
The ophthalmologist closes the incision using sutures or a self-sealing technique that does not require sutures. After the surgery is finished, the patient is monitored for a short period of time to ensure that there are no complications. The patient may experience some discomfort, redness, and sensitivity to light in the days following the surgery, but these symptoms usually subside within a few days.
An incision is made in the cornea using a sharp blade or a laser. The size of the incision depends on the surgeon’s preference, but it is usually between 5 and 8 millimeters.
Once the incision is made, the surgeon creates a circular opening in the front of the lens capsule using a small needle or forceps. This is called a capsulorhexis.
The surgeon then uses a small instrument called a phacoemulsifier to break the cataract into smaller pieces and suction them out of the eye through the incision. This is done using ultrasound waves.
Once the cataract is removed, the surgeon inserts an artificial intraocular lens (IOL) into the eye to replace the natural lens. The IOL is folded and inserted through the same incision used for the phacoemulsification.
After the IOL is inserted, the surgeon may need to suture the incision closed. In some cases, the incision may be self-sealing, and no sutures are required.
Recovery time for extracapsular cataract extraction surgery can vary, but most patients feel comfortable enough to resume normal activities within a few days.
After the procedure, an eye patch may be applied to protect the eye and reduce swelling. This patch may need to be worn for a few days.
Patients may be given eye drops or other medications to prevent infection and control inflammation.
Patients need to attend regular follow-ups with their surgeon to monitor the healing process and ensure that the IOL is properly positioned.
Patients should not drive until they are cleared by their surgeon, which may take several weeks.
There is a risk of infection. Patients may be prescribed antibiotics to reduce this risk.
Bleeding is rare but possible.
In some cases, patients may experience swelling and inflammation in the eye after surgery. This can usually be managed with medication.
There is a small risk of retinal detachment after extracapsular cataract extraction surgery.
In rare cases, the IOL may become dislocated after surgery. This may require additional surgery to correct.
Patients may develop glaucoma after extracapsular cataract extraction surgery. This can usually be managed with medication.
