Cataracts are one of the most common eye complaints and typically occur in people over 55. In the past, the only treatment available to patients was lens replacement surgery. However, with current advances in technology, laser surgery is now an effective alternative to a cataract surgery lens and is also effective at curing other eye conditions. To help you decide which is the best option for you, here is a simple guide to laser surgery and lens replacement surgery.
What is lens replacement surgery?
Lens replacement surgery involves surgically removing the damaged part of the lens and replacing it with an artificial lens, also known as an intraocular lens (IOL). In previous years, a cataract surgery lens was made from clear medical-grade Perspex and suitable only for repairing cataracts. However, lens replacement technology has advanced over the years to a point where artificial lenses can be designed for a variety of vision problems in addition to cataracts.
Benefits of lens replacement surgery
Lens replacement surgery is considered the most effective way to treat a cataract as the surgery fully removes the affected lens and leaves no chance of the cataract returning. Nearly all patients with cataracts or refractive eye conditions are eligible for lens replacement surgery, and with the lens designed to correct multiple vision conditions, lens replacement surgery is an excellent alternative to wearing glasses or contact lenses.
Drawbacks to lens replacement surgery
As with any invasive surgery, there can be complications that increase your recovery time or require additional treatments. Some complications can include infection, macular edema, retinal detachment, or posterior capsule opacity. Complications are rare, and most are easily fixed. However, always contact your doctor if you notice any unusual symptoms.
What is laser surgery?
There are many different types of laser surgery for the eye. However, two of the most popular procedures are LASIK and SMILE. During a laser procedure a surgeon uses either a laser or an ultra-thin blade to create a flap in the cornea, then they use another laser to remove corneal tissue to reshape the cornea to repair the refractive vision issues.
Benefits of laser surgery
The single biggest benefit to opting for laser surgery is that it is less invasive than a lens replacement. It also has fewer side effects and complications. Laser surgery has also been shown to be more effective than lens replacement surgery for most refractive conditions.
Drawbacks of laser surgery
Some eye conditions or diseases such as diabetes or glaucoma exclude laser surgery as an option. Or, the necessary corneal tissue removal is too extensive for a laser to be effective.
