The human eye is a remarkable organ, allowing us to experience the world in all its beauty. However, like any part of the body, the eyes can encounter issues that may require surgical intervention to maintain or restore vision. Read on as we explore some of the most common eye surgical procedures, shedding light on how they work and the conditions they address.
LASIK (Laser-Assisted In Situ Keratomileusis)
LASIK surgery is one of the most well-known eye procedures around the world, offering freedom from glasses and contact lenses for many. This refractive surgery reshapes the cornea, the clear front surface of the eye, to correct nearsightedness, farsightedness, and astigmatism. During LASIK, a microkeratome or femtosecond laser creates a thin flap in the cornea, which is then lifted to allow the laser to reshape the underlying tissue. The flap is repositioned, and the eye heals naturally.
Approximately 96% of those who undergo a LASIK procedure successfully achieve excellent vision and those who don’t still observe noticeable enhancements in their visual clarity and reduced dependence on eyeglasses or contact lenses.
Cataracts occur when the natural lens of the eye becomes cloudy, causing blurry vision. Cataract surgery is the most frequently performed surgical procedure globally. It involves removing the clouded lens and replacing it with an artificial intraocular lens (IOL). Modern cataract surgery is often done using phacoemulsification, a technique that uses ultrasound energy to break up the cloudy lens for easier removal.
Glaucoma is a condition characterised by increased intraocular pressure, which can damage the optic nerve and lead to vision loss. Various glaucoma surgeries aim to lower this pressure. Trabeculectomy, for example, involves creating a new drainage channel to allow excess fluid to escape, reducing pressure. Minimally invasive techniques like laser trabeculoplasty and microinvasive glaucoma surgery (MIGS) are also used to manage glaucoma.
Retinal Detachment Surgery
A retinal detachment occurs when the retina, the light-sensitive layer at the back of the eye, pulls away from its normal position. Surgical procedures like pneumatic retinopexy, scleral buckling, and vitrectomy are used to reattach the retina. These surgeries often require precise techniques and skilled ophthalmic surgeons to ensure the retina is successfully repositioned.
Corneal Transplant (Keratoplasty)
Corneal transplants involve replacing a damaged or diseased cornea with healthy donor tissue. There are different types of corneal transplants, including full-thickness (penetrating) keratoplasty and partial-thickness (lamellar) keratoplasty. These procedures can restore clear vision in individuals with conditions like keratoconus, corneal scarring, and Fuchs' dystrophy.
Oculoplastic surgery addresses cosmetic and functional issues around the eyes and includes procedures like eyelid surgery (blepharoplasty), ptosis repair (correcting drooping eyelids), and tear duct surgery (dacryocystorhinostomy). These surgeries not only enhance aesthetics but also improve vision and comfort.
Eye surgery has come a long way in recent decades, offering highly effective solutions for a wide range of eye conditions. Before considering any surgical procedure however, it's essential to consult with both your optoometrist and recommended ophthalmologist to discuss your specific needs and explore the most suitable options for you. With the right procedure and expert care, you can look forward to a brighter and clearer future.
