LASIK surgery is an ambulatory procedure which only takes less than five minutes and performed while you are fully awake. As quick as it may be, it is important to remember that you should have someone with you to assist you after the surgery.
Laser eye surgery only needs topical anesthesia – numbing eye drops will be used before the treatment to relieve you of any discomfort.
With your eye under the laser, your eye surgeon will create a thin, circular corneal tissue. The surgeon will then access the underlying cornea and remodel it to correct imperfections based on your particular prescription. Lastly, the flap is put back in place and the cornea is allowed to heal naturally. The procedure is done one eye at a time.
Immediately after the surgery, patients are highly advised to rest and get a long sleep for faster recovery. Temporary discomfort after the surgery will be relieved through antibiotic and anti-inflammatory eye drops. Haziness or blurry vision is normal but it should be gone the next day. Avoid doing strenuous activities that might affect the healing. Other post-operation care include wearing protective goggles to prevent rubbing or a darkened pair of shields to protect the eyes from bright lights. For most patients, dramatic results can be seen the next day.
As with any other medical procedure, follow the surgeon’s prescriptions and return for a follow-up checkup to have your progress recorded.
Vision Correction Procedures
Eyesight problems can now be addressed using different solutions such as eyeglasses, contacts or the laser eye surgery like Femto Lasik. Whatever your option is, it is best that you talk to an eye specialist to know which procedure is best for your condition.
LASIK vision correction: The most common type of laser vision correction procedure, LASIK is virtually painless and quick-healing.
Wavefront Optimized® LASIK: A unique form of LASIK offered exclusively by Femto Lasik™, Wavefront-Optimized® LASIK uses laser energy in the corneal periphery while taking into account the curvature and thickness of the cornea. Complications from conventional treatments such as glare and halos are reduced using this procedure.
Wavefront-guided LASIK: A type of LASIK that uses a special “mapping” of the eye to create a personalized treatment for each patient. Femto Lasik™ offers Wavefront-Guided treatment in addition to Wavefront-Optimized LASIK.
Excellent Visual Acuity
The WaveLight® Allegretto Wave® Lasers customize every treatment to the patient’s individual prescription and cornea while aiming to improve what nature originally designed. The proprietary Wavefront Optimized® treatment considers the unique curvature of the eye, preserving quality of vision and addressing the spherical distortions that may induce glare and affect night vision.
The Principle Behind Wavefront Optimized® Treatments
The natural shape of the human cornea is aspheric. This means that all light rays meet in one sharp focus point. Therefore, the laser systems perform an ablation with the objective to maintain a natural post-operative corneal shape and thus to preserve the cornea’s aspheric shape. Every treatment is customized to the patient’s individual refraction and corneal curvature by taking the K-readings into consideration.
Understanding spherical aberrations:
Spherical aberrations manifest at in-going light rays in the periphery. Wavefront Optimized® treatment profiles keep the natural aspheric shape of the cornea, hence all ingoing light rays meet in one point. Non-aspheric ablations change the corneal aspheric shape and the light rays from the periphery are focused in different points which may lead to a slightly blurry image and night vision disturbances.
Aspheric shape, minimized spherical aberrations
Induced spherical aberrations
Spot energy of laser beam
Due to the angle of incidence the light of the laser beam is ovalized increasingly towards the periphery and becomes partially reflected which results in less fluence and thus sub-optimal ablation.
Wave front Optimized® ablation profile
Wave front Optimized® LASIK places more pulses in the peripheral area to compensate for energy loss and reflections. This provides a nearly 100% optical zone and a minimized transition zone. At the same time, the natural aspheric shape of the cornea is preserved and the induction of spherical aberrations minimized.
Without Wavefront Optimized® ablation profiles
In these treatments the decreasing fluence and reflections are not compensated and the ablation depth in the peripheral area is insufficient. As a result, the transition between the optical zone and the transition zone is less smooth, while the transition zone itself is fairly large. The non-aspheric ablation profile alters the natural corneal shape and induces spherical aberrations.
ARE YOU A CANDIDATE?
Before performing laser surgery, series of tests will have to be conducted to make sure that you qualify for the treatment. Below are few simple questions to help you find out if you are a good candidate for LASIK surgery.
This test is completely free and all the information you provide will be strictly confidential and only the doctor will have access to it. Please make sure to enter all the information as accurate as possible. After analyzing your details, we will respond to you by phone or email.
