Cataracts occur when the eye lens becomes cloudy, resulting in decreased vision. This condition affects tens of millions of people worldwide and can affect one or both eyes. It can cause faded colors, halos around lights, blurry or double vision, and difficulty seeing in the dark. Age and general diseases, such as diabetes, medicine on long-term bases, or eye injury, are among the risk factors for cataracts.
Cataracts can lead to trouble driving, reading, or even recognizing faces, and may cause depression. Cataracts are responsible for 50% of all cases of blindness worldwide, affecting over 20 million people. Luckily, modern medicine offers effective treatment through cataract removal, which involves replacing the clouded lens with an artificial one. The success rate of this surgery is promising, with nine out of ten patients achieving at least 20/40 vision after the operation.
CATARACT REMOVAL IS PERFORMED UNDER LOCAL ANESTHESIA AND IS USUALLY COMPLETED WITHIN TEN MINUTES. THE SURGEON USES ULTRASOUND TO CRUSH THE CLOUDY LENS, WHICH IS THEN PAINLESSLY REMOVED THROUGH A MICROINCISION. A NEW, HIGH-QUALITY LENS IS IMPLANTED TO REPLACE THE FAULTY LENS. ANTIBIOTICS MAY BE INJECTED INTO THE EYE TO REDUCE THE RISK OF INFECTION. AFTER THIS PROCESS, SALTWATER IS INJECTED INTO THE CORNEAL WOUNDS TO SEAL THE INCISION.
The standard method of cataract surgery involves a small incision, a subtenon injection or anesthetic eye drops, corneal incision, capsulorhexis, handheld ultrasonic probe, emulsification of the lens, and the insertion of a synthetic lens into the capsular bag. Another option is a laser-assisted operation, where the incision is performed by laser.
The femtosecond laser is capable of making precise incisions, which can result in better outcomes for the patient. Additionally, the laser can also assist with creating the capsulorhexis, breaking up the lens, and correcting astigmatism.
Overall, the laser-assisted method can offer greater precision, less invasion, and faster healing times compared to the standard method. However, it is important to note that the laser-assisted method may not be suitable for all patients and their individual circumstances.
In conclusion, a cataract is a common eye condition that affects millions of people worldwide. It is caused by the clouding of the lens, which can lead to a decrease in vision and even blindness if left untreated.
Thankfully, modern medicine has made it possible to remove cataracts through surgery, which is a safe and effective treatment method. Patients can choose between the standard method or the laser-assisted method, depending on their individual circumstances and preferences.
If you are experiencing symptoms of cataracts, it is important to consult with an eye doctor for a proper diagnosis and treatment plan. Early detection and treatment can prevent further damage to your vision and improve your quality of life.
