LASIK and PRK

LASIK and PRK are refractive surgeries that aim to correct vision problems like myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.

• LASIK (Laser-Assisted In Situ Keratomileusis) involves creating a thin flap in the cornea using a microkeratome or a femtosecond laser. The flap is then lifted, and the underlying corneal tissue is reshaped using an excimer laser to correct the refractive error. The flap is then repositioned, and it adheres naturally to the cornea.
• PRK (Photorefractive Keratectomy) involves removing the outer layer of the cornea (epithelium) and then reshaping the underlying corneal tissue using an excimer laser. The epithelium regenerates over a few days, and the new corneal shape corrects the refractive error.

Both LASIK and PRK have their own benefits and risks.

Benefits and Risks of LASIK and PRK

• LASIK
  • Benefits: Faster visual recovery, less postoperative discomfort, and a more predictable outcome.
  • Risks: Dry eyes, flap complications (e.g., flap dislocation, flap infection), ectasia (thinning of the cornea), and undercorrection or overcorrection of vision.
• PRK
  • Benefits: Lower risk of ectasia, suitable for thin corneas, and better for patients with high refractive errors.
  • Risks: Slower visual recovery, more postoperative discomfort, and a higher risk of infection.

Advancements in LASIK and PRK Technology

• Wavefront-Guided LASIK is a customized approach to LASIK that uses wavefront technology to map the unique shape of the cornea and create a personalized treatment plan. This technology allows for a more precise and accurate correction of refractive errors, resulting in improved visual acuity and reduced risk of complications.

Cataract Surgery

Cataract surgery is a procedure to remove a cloudy lens (cataract) from the eye and replace it with an artificial lens (intraocular lens, IOL).

Types of Intraocular Lenses (IOLs)

• Monofocal IOLs: These lenses provide clear vision at one distance (usually distance vision). They are the most common type of IOLs.
• Multifocal IOLs: These lenses provide clear vision at multiple distances (near, intermediate, and far), reducing the need for reading glasses or bifocals.
• Toric IOLs: These lenses are designed to correct astigmatism, a condition where the cornea has an irregular shape.
• Accommodative IOLs: These lenses allow the eye to focus at different distances, similar to the natural lens. However, their effectiveness is still under investigation.

Benefits of Advanced IOLs

• Multifocal IOLs can provide independence from glasses for most daily activities.
• Toric IOLs can eliminate the need for astigmatism correction with glasses or contact lenses.

Latest Techniques in Cataract Surgery

• Femtosecond Laser-Assisted Cataract Surgery is a minimally invasive technique that uses a femtosecond laser to create precise incisions in the cornea and to break up the cataract. This technique offers several benefits, including faster recovery time, improved accuracy, and reduced risk of complications.

Glaucoma Surgery

Glaucoma is a condition that damages the optic nerve, which connects the eye to the brain. This damage can lead to vision loss. Glaucoma surgery aims to lower the pressure inside the eye (intraocular pressure), which is a major risk factor for glaucoma.

Types of Glaucoma Surgery Procedures

• Trabeculectomy: This procedure involves creating a small flap in the sclera (white part of the eye) and removing a portion of the trabecular meshwork, a tissue that helps drain fluid from the eye. This creates a new drainage pathway for the fluid, reducing intraocular pressure.
• Tube Shunts: These devices are implanted in the eye to drain fluid from the eye and reduce intraocular pressure.
• Laser Trabeculoplasty: This procedure uses a laser to create small burns in the trabecular meshwork, improving the drainage of fluid from the eye.

Latest Developments in Minimally Invasive Glaucoma Surgery (MIGS)

• Micro-shunts are tiny devices that are implanted in the eye to improve the drainage of fluid. They are less invasive than traditional glaucoma surgeries and have a faster recovery time.

Retinal Surgery

Retinal surgery focuses on treating diseases affecting the retina, the light-sensitive tissue at the back of the eye.

Advancements in Retinal Surgery Techniques

• Vitrectomy is a procedure that removes the vitreous gel, the clear jelly-like substance that fills the back of the eye. This procedure is used to treat a variety of retinal conditions, such as retinal detachment, macular holes, and diabetic retinopathy.
• Macular Hole Repair involves closing a hole in the macula, the central part of the retina responsible for sharp central vision. This procedure can help restore vision in patients with macular holes.

Use of New Technologies in Retinal Surgery

• Intravitreal Injections are used to deliver medications directly into the vitreous gel. These injections are used to treat a variety of retinal conditions, such as diabetic retinopathy, macular degeneration, and retinal vein occlusion.
• Retinal Implants are devices that are implanted in the retina to stimulate the optic nerve and restore vision in patients with severe vision loss. These implants are still in the early stages of development, but they hold great promise for the future of retinal surgery.

Role of Lasers and Imaging Techniques in Retinal Surgery

• Lasers are used in retinal surgery to treat a variety of conditions, such as diabetic retinopathy, macular degeneration, and retinal tears. They can also be used to seal blood vessels and destroy abnormal tissue.
• Imaging Techniques, such as optical coherence tomography (OCT) and fundus photography, are used to diagnose and monitor retinal diseases. These techniques provide detailed images of the retina, allowing surgeons to plan and perform surgery more effectively.

Another significant advancement is the development of presbyopia-correcting IOLs (intraocular lenses). Presbyopia, the age-related loss of near vision, is a common vision problem that affects people over 40. Presbyopia-correcting IOLs are implanted during cataract surgery and can restore both near and far vision.

“Since having the surgery, I can see clearly without glasses or contact lenses. I can read, drive, and enjoy all my favorite activities without any vision limitations.” – John, a patient who underwent LASIK surgery.
