LASIK/PRK Surgery in Dallas, TX
What is Laser Eye Surgery?
Refractive surgery at Infinity Vision in Dallas, TX aims to correct nearsightedness (Myopia), farsightedness (Hyperopia) and astigmatism. Radial Keratotomy (RK) was the desired procedure used to correct refractive errors until the Excimer Laser was approved for use in 1995. Two procedures are performed with the use of the Excimer Laser: laser-assisted in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK). The excimer laser reshapes the corneal surface by ablation of the stromal tissue thus correcting varying degrees of myopia, hyperopia, and astigmatism.
Difference between Lasik and PRK
LASIK uses two types of lasers:
- An excimer laser to reshape the cornea
- Emtosecond laser (IntraLase) to make a bladeless corneal flap
PRK only uses the excimer laser to treat the surface of the cornea.
Both LASIK and PRK are effective in eliminating or dramatically reducing dependence on glasses or contact lenses. Wavefront or Custom LASIK and PRK uses sophisticated imaging of the cornea to achieve the highest quality of vision possible.
Intraocular lens implantation is sometimes recommended for correction of refractive errors as well. LASIK or PRK has often used to fine-tune the refractive results of previous cataract surgery.
Who is a good candidate for LASIK?
The first step in considering an individual’s eligibility for LASIK is to do a detailed evaluation of their eyes. Though this procedure is deemed safe, it is also important for LASIK candidates to fully comprehend all of the risks associated with the procedure and to keep reasonable expectations in regard to the results. The ideal candidate for LASIK is someone who meets the following qualifications:
- Over the age of 18 years old
- Not currently pregnant or nursing
- Is overall healthy
- Has had an unfaltering vision in the past 6 months or more
- Has a healthy, thick corneal tissue
- Has a treatable refractive error
The patient is positioned in a reclining chair directly under the exciplex laser. A speculum is utilized to keep the individual’s eye open as it is cleaned and anesthetic eye drops are dispensed to diminish discomfort. After creating a corneal flap with either a blade or laser, the surgeon will enable the laser to adjust the curvature of the cornea by delicately lifting the surface of the cornea. The laser delivers customized amounts of light energy to the patient’s eyes, one directly after the other.
This procedure takes less than 5 minutes to complete but the patient should expect to stay at the ophthalmologist office for a few hours.
The patient pre-arranges an escort home after surgery. Because discomfort is normal for up to 48 hours after surgery, medication may be prescribed. Although told to avoid laborious work for 7 days, patients may return to their jobs the next day after surgery.
Vision improvement is typically immediate after LASIK but the full benefits may not be felt until months later. This procedure does allow for clear vision but it does not stop the development of presbyopia, which may cause individuals over 40 to need reading glasses.
Took time to explain every detail of the surgery. Asked questions when finished to make sure you understood the procedure. Return visits I was treated as if it was my first visit. He spent quality time every time. One of the nicest physicians I have seen in a very long time. Would recommend him to my friends.
Wonderful Office and staff. Tony Hamilton is wonderful. Dr. Russell and his staff are the best.
