Specs Removal/Lasik

Imagine life without contacts or glasses. You can see clearly in bright, vibrant color. You no longer have to squint. Activities like hiking, biking, swimming, tennis and golf are much more convenient because you don’t have to worry about losing a contact lens or your glasses sliding down your nose. For many, LASIK is helping people become less dependent on contacts and glasses. However, while LASIK can be an amazing procedure, your decision on where to go should not be made lightly. The surgeon you choose can mean the difference between excellent results or real complications.

How the eye works Understanding vision

The human eye is truly remarkable in its design. Each eye is unique. Each eye condition is also unique. Vision quality is largely determined by the size and shape of our eyes. With a healthy eye, light rays entering the eye are focused directly on the retina to form a sharp image, which is then sent to the brain via the optic nerve, resulting in a visual image. When the eye’s dimensions are not well-aligned, the light rays are not correctly focused. This results in a refractive error such as nearsightedness, farsightedness and astigmatism (an irregular curvature of the cornea). Refractive errors are very widespread and affect people of all ages. Normal vision With normal vision, the eye’s dimensions are well-aligned. Light rays are focused directly on the retina to create a clear image.

Understanding Refractive Errors

Clear vision in the normal eye is the result of light rays passing through the cornea, pupil and lens and focusing directly on the retina.

Clear vision

in the normal eye is the result of light rays passing through the cornea, pupil and lens and focusing directly on the retina.

Nearsightedness (Myopia)

occurs when the cornea is too curved or the eye is too long. This causes light to focus in front of the retina, resulting in blurry distance vision.

Farsightedness (Hyperopia)

occurs when the cornea is too flat in relation to the length of the eye. This causes light to focus at a point beyond the retina, resulting in blurry close vision.

Astigmatism

occurs when the cornea is shaped like a football (more curved in one direction than the other) and often occurs with nearsightedness and farsightedness. This causes light to focus in more than one point on the retina, resulting in blurry and distorted vision.

Types of refractive surgery

Laser In Situ Keratomileusis (LASIK)
Photorefractive Keratectomy (PRK)
Small Incision Lenticule Extraction (SMILE)
Phakic Intraocular Lenses (IOLs)
Corneal Inlays
Clear Lensectomy
Intracorneal Ring Segments (INTACS)
Radial Keratotomy and Astigmatic Keratotomy

Corneal refractive surgery alters the curvature of the cornea to focus light more precisely on the retina. The goal of refractive surgery is to decrease dependence on eyeglasses or contact lenses. Most people who undergo refractive surgery achieve this goal; over 95% do not need corrective lenses for distance vision. Ideal candidates for refractive surgery are healthy people aged 18 and older with healthy eyes who are not satisfied wearing eyeglasses or contact lenses.

Contraindications to refractive surgery include

Active ocular diseases, including severe dry eye
Autoimmune or connective tissue diseases, which can impair wound healing
Use of isotretinoin or amiodarone Refraction should be stable for at least 1 year prior to surgery. Latent herpes simplex virus may be reactivated after surgery; patients should be advised accordingly.

Adverse effects of refractive surgery include temporary symptoms of

Foreign body sensation
Glare
Halos
Dryness

Potential complications include

Overcorrection
Undercorrection
Infection
Irregular astigmatism The overall complication rate is low; chance of vision loss is < 1% if the patient is considered a good candidate for refractive surgery preoperatively.

Laser In Situ Keratomileusis (LASIK)

Characteristics of LASIK and Femto-LASIK
Since its introduction in the early 1990s, laser-assisted in-situ keratomileusis, or LASIK for short, has become the most widely performed laser treatment method for correcting refractive errors.

KEY POINTS

Generally quick visual recovery
Most frequently performed procedure
Treatment standard for more than 20 years
Widely available and performed by many surgeons
Femto-LASIK: the entire procedure is done with lasers only

Comparing the two proven procedures

Treatment steps of LASIK and Femto-LASIK

With traditional LASIK, a controlled blade (microkeratome) is used to create the flap (a kind of hinged piece of corneal tissue). With advanced bladeless Femto-LASIK, a highly precise flap is quickly created with a femtosecond laser. Prior to treatment Anesthetic eye drops are applied to the eye. An eyelid holder prevents the eye from blinking during the procedure.

Creating the flap

The microkeratome creates a flap, a hinged corneal piece of tissue.

Folding back the flap

The flap is gently folded back, exposing the inner corneal tissue to be treated

Correcting the error

An excimer laser reshapes the corneal tissue, correcting the refractive error.

Repositioning the flap

The flap is returned to its original position, protecting the eye like a natural bandage

Photorefractive Keratectomy (PRK)

In PRK, unlike laser in situ keratomileusis (LASIK), no corneal flap is created. In PRK, the corneal epithelium is removed and then the excimer laser is used to sculpt the anterior curvature of the corneal stromal bed. PRK is used to treat myopia, hyperopia, and astigmatism. The epithelium typically takes 3 to 4 days to regenerate; during this time a bandage contact lens is worn. PRK may be more suitable for patients with thin corneas or epithelial basement membrane dystrophy.

Phakic Intraocular Lenses (IOLs)

Phakic IOLs are lens implants that are used to treat moderate to high (eg, 4 to 20 diopters) of myopia with or without astigmatism in patients as an alternative to laser vision correction. Phakic IOLs achieve superior visual quality compared to laser vision correction because they do not alter the corneal curvature. Also, there is no risk of corneal ectasia since this is additive technology and no corneal stromal tissue is ablated. Unlike in cataract surgery, the patient’s natural lens is not removed. The phakic IOL is inserted directly anterior or posterior to the iris through an incision in the eye. This procedure is intraocular surgery and must be done in an operating room.

Corneal Inlays

Corneal inlays are implants placed into the corneal stroma via a lamellar pocket or flap to treat presbyopia. The only corneal inlay available in the US is made of polyvinylidene fluoride and carbon and is a small aperture inlay, which improves near vision by increasing depth of focus. These inlays are placed only in the nondominant eye of presbyopic patients.

Intracorneal Ring Segments (INTACS)

INTACS are thin arc-shaped segments of biocompatible plastic that are inserted in pairs through a small radial corneal incision into the peripheral corneal stroma at two-thirds depth. After INTACS are inserted, the central corneal curvature is flattened, reducing myopia. INTACS are used to treat mild myopia (< 3 diopters) and minimal astigmatism (< 1 diopter). INTACS maintain a central, clear, optical zone because the 2 segments are placed in the corneal periphery. INTACS can be replaced or removed if desired.
