Today, modern refractive surgery delivers very satisfying visual results. However, prior to your LASIK eye surgery, doctors need to ensure that you are a suitable candidate for the surgery after carrying out basic vision testing, fundus evaluation and certain eye scans. Apart from being a healthy individual, a person undergoing surgery should be at least 18 years old.
Some eye conditions like ocular injuries, cataracts, keratitis, glaucoma, uveitis, progressive vision deterioration, etc., can cause post-surgical complications or interfere with the outcome of the LASIK eye surgery. Hence, it is crucial to get a screening test for LASIK eye surgery and resolve certain complications before the LASIK eye operation.
Refractive surgery gives better results in people with stable vision. The visual impairment (spectacle power) should not have changed fundamentally in the past year, which can be known with a refractive eye test. Any change in prescription glasses every 12 months may result in a disappointing outcome with surgery and residual refractive / spectacle power.
Pregnant or breastfeeding women undergo significant changes in their bodies, including their eyesight. Having a stable vision is crucial to reap maximum benefits from the surgery. Also, some pregnant women can experience medical conditions like diabetes and preeclampsia, which increases the chances of failure of the LASIK eye operation.
As contact lenses change the structure of the cornea, it hampers accurate measurements and may lead to poor results post LASIK eye surgery.
In case of high prescription, your eye surgeon may need to remove more corneal tissue to correct the vision. Abnormal thinning of the cornea may cause corneal ectasia post LASIK eye surgery.
Laser-assisted in situ keratomileusis (LASIK) eye surgery, also known as ‘laser refractive surgery’, is a popular method for vision correction. LASIK eye surgery is a popular alternative to contact lenses or prescription glasses.
LASIK eye surgery is a painless yet effective choice of treatment for those who suffer from eye conditions like nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. LASIK eye operation involves the correction of the refractive power of the eye with the help of a specialized cutting laser that precisely and permanently reshapes the cornea, which ultimately results in improved vision.
Today, millions of people worldwide choose this elective LASIK eye surgery to enjoy better and improved vision without having to wear glasses or contact lenses. Check with your LASIK surgeon to know whether you are a suitable LASIK surgery candidate.
Photorefractive Keratectomy (PRK) is a popular type of refractive laser eye surgery in which the superficial layer of the cornea is gently scraped off to gain access to the area that has to be treated . With the help of a laser, vision problems are treated that are caused by refractive errors of the eye.
The quality of life is affected when a person faces refractive errors of the eye in which eyes fail to bend light properly. However, with PRK surgery, the shape of the cornea is changed in such a way that light rays are properly focused on the retina.
You may not need glasses or contact lenses after PRK surgery, at least for certain activities. During this procedure, the cornea's outer layer is swabbed away gently, which offers easy access to the treatment area. This thin epithelium layer regenerates after the operation naturally. Hence, due to the nature of the surgery, PRK needs a more prolonged recovery duration than LASIK eye surgery.
PRK is a safe and effective procedure for people with thin corneas or other restrictions that may prevent them from undergoing LASIK eye surgery. However, the results of the PRK eye procedure appear gradually, and it takes time to stabilize vision improvements.
With FEMTO LASIK eye surgery, it is now possible to correct visual impairments permanently. Today, it is a commonly used procedure to improve the refractive power of the eye and correct issues like longsightedness of up to +4 dpt, the shortsightedness of up to -8 dioptres (dpt), and astigmatism of up to 6 dpt.
Femtosecond laser used in vision correction surgery increases both accuracy and precision of flap making. Hence, it is popularly known as ‘bladeless LASIK eye surgery’.
The ReLEx smile treatment is an advanced version of FEMTO-LASIK eye surgery that improves the refractive power of the eye and enables the correction of ametropia. With the help of state-of-the-art femtosecond technology and high-precision lenticular extraction, visual errors like dry eyes, myopia, and astigmatism are easily corrected.
The benefit of using the ReLEx smile is that it does not involve ‘flap folding’ or a big opening of a corneal area. Instead, this minimalist procedure uses a special femtosecond laser to make a thin 3-D lenticular disc inside the cornea. In addition, this is a safe procedure that protects the eye and preserves cornea and corneal nerves, further excluding flap complications.
Patients who are not suitable for LASIK eye surgery can opt for alternative procedures in consultation with their eye doctors to improve their quality of life and vision. To correct refractive errors of the eye, the Visian ICL procedure is perfect. The Visian ICL procedure is an excellent option for those suffering from moderate-to-severe nearsightedness with or without astigmatism, severe dry eye, or thin corneas.
Implantable Collamer Lens (ICL) is gaining tremendous popularity in refractive surgery as it comprises 100% biocompatible collagen copolymer. The soft-material lens offers protection from harmful UV rays and sharper, clearer vision.
Unlike LASIK eye surgery that permanently changes the shape of the cornea, ICL is an innovative technology that implants a soft lens in the eye and needs no minimum corneal thickness. In addition, the lens demands no maintenance, and the implantation is reversible.
Refractive lens exchange or lens replacement surgery is an effective vision correction procedure that involves the removal of a patient's natural crystalline eye lens and replacing it with an artificial intraocular lens (IOL). In this procedure, the optical properties of the used lens correct the refractive errors of the eye. Refractive lens exchange is an excellent procedure for correcting shortsightedness, long-sightedness, and astigmatism.
Your LASIK eye surgery best doctors can ensure that you are a suitable candidate for the lens replacement surgery, if,
