Different Types of Laser Cataract Surgery

Many people want to know if they need "laser surgery" after undergoing cataract surgery. In fact, many people are actually confused about "laser surgery" and cataract surgery. In fact, modern cataract surgery performed in an eye clinic in Malaysia is usually does not involve lasers. Instead, a microscopic device (phacoemulsification probe) is used to break down and remove the turbid/cloudy lens from the patient's eye. After removing the cloudy lens, an artificial intraocular lens implant (IOL) was placed in the eye. However, in most cases, the laser does not participate in this process.
Laser cataract surgery may have some benefits after cataract surgery. The most common is the development of posterior capsular opacification (PCO), which can grow on the residual lens structure behind the IOL. This paralyzed PCO can partially block the light of the intraocular lens, obscure the patient's vision, and cause blurred blemishes or glare. PCO is actually the most common complication after routine cataract surgery. If it becomes large enough to limit the functional vision of the patient, it is usually treated with an instrument called an Nd: YAG laser.

This type of laser has existed for several decades and has been very accurate and successfully removed the PCO with slight discomfort and the shortest recovery time. The Nd: YAG laser can be very carefully aimed at the back of the intraocular lens to remove the PCO area and create a clear path for the passage of light. This procedure is usually less than five minutes.

From the patient's point of view, this is actually very simple. The doctor puts plastic "contact lenses" on your eyes to keep your eyes open and enable him to focus the laser beam. Then he carefully aimed the laser to cut a small, clear circular area on the PCO. Despite the bright light, the patient hardly felt anything. Nd: YAG laser cataract surgery has been very successful in restoring visual acuity to high levels.
