First of all, you should have an eye exam in a licensed eye clinic to see if you are a candidate for lasik eye surgery. If the patients’ vision is not stable, they will not be a suitable candidate for lasik eye surgery. This is also the reason why people under 21 years old or those whose hormones are fluctuating are recommended not to have lasik or any other kind of refractive eye surgery performed. There is about 6% of the American population who have carried out laser eye surgery may have a not favorable result. Some of them may need another eye surgery, but it is not advisable to proceed. Besides, patients who are pregnant or have weakened immune systems are also on the name list of unsuitable people for laser eye surgery. And the patients’ health history, especially any eye injuries or eye diseases, should also provide to the eye doctor to help him judge if you are suitable to undergo the eye surgery.

Then you should discuss the procedure of the eye surgery with your eye surgeon to find a best lasik eye surgery for yourself. For instance, what kind of eye surgery will be performed? Which instrument or laser techniques will be used? It is also important to know the possible complications of the lasik eye surgery sufficiently.

Finally, you should know the cost of each kind of eye surgery. It commonly varies greatly depending on the instrument, techniques, eye doctor, and eye clinic you choose and the condition of your eyes.

You may find the information on the internet or from any local eye clinic.

Contact Lens Types 

- Soft Lenses: The most commonly prescribed contact lens are these gel-like containing plastics the size of the iris of the eye. More recently, the silicone hydrogel lenses have been introduced and are generally preferred by practitioners since they allow more oxygen to pass between the lens and the eye and are less likely to dry out. 

- Hard Lenses: Made from PMMA, which is plexiglass or lucite, these lenses are almost never used anymore but may be preferred or required by the patient. 

- GP or RGP Lenses: These are “oxygen permeable” lenses that are stiff, waterless plastics geared toward patients with presbyopia and a high astigmatism and a smaller than the iris of the eye. 

Contact Lens Wear

- Daily Wear contacts can be worn throughout the day but must be removed and cleaned nightly. Daily wear contact lenses come in different durations of wear time and must be eventually disposed of and replaced with a fresh pair. There are contacts that are disposed of daily, weekly or monthly depending on the preference as well as the visual needs of the patient. 

- Extended Wear contacts can be safely worn overnight or up to 7 consecutive days without removal. Continuous wear lenses are a type of extended wear that can be worn for up to 30 consecutive nights without removal.

There are also contact options available for more severe eye diseases and may need to be custom made to fit and serve the purpose of a special needs situation. Almost anyone these days can wear contacts, in fact 1 out of 5 people in the U.S. is a contact lens wearer. Whether the purpose for contact lens wear is a replacement to glasses or for more aesthetic purposes there is bound to be a healthy contact option available for everyone.

Diabetes is always accompanied by high sugar levels, which may damage the blood vessels of the body, especially those in the eyes. Studies have found that excess amounts of blood sugar caused by diabetes can significantly increase the risk of several eye diseases, including cataracts, blood leakage in the retina, macular edema, macular degeneration, and glaucoma as well as eye infections. Associated with so many possible diseases, diabetes has become a top cause of blindness among US citizens.

Natural aging is inevitable in everyone. Vision loss at different degrees is quite common among old people, especially in those above 50. Vision loss caused by natural aging is always gradual and not noticeable. Yet there are still other health conditions that indirectly or directly affect eyesight in older individuals. Those factors include uncontrolled diabetes, high blood pressure, kidney disease, cataracts, AMD, retinal tears and detachment, glaucoma, diabetic retinopathy as well as presbyopia.

There is a great population of smokers in the world. Unfortunately, most people are not aware of the deleterious effects of smoking on the eyes. Smoking has been thought to increase the risk of macular degeneration and cataracts. This bad habit influences eye health by affecting oxygen level in the ocular tissues. Smoking makes a smoker’s heart to work harder and raise blood pressure, which becomes less efficient in delivering sufficient oxygen to the eyes.

High blood pressure in the eyes can lead to small leaks and clots. Blood leakage in surrounding eye tissues usually affects focus ability. And clots in the eye consume precious oxygen and even cause vision loss. Contributors of high blood pressure include heart disease, diabetes, and unresolved renal disease.

Nutrition also plays an important role in maintaining good eye health. People should regularly consume beneficial nutrients such as anti-oxidants including vitamin A, C and E as well as healthy fats such as omega-3 acids. A lifelong unhealthy diet can speed up aging process.

Some common visual disorders that can be cured with refractive eye surgery include myopia and astigmatism. Due to the high prevalence of such eye diseases, a very high number of refractive eye surgeries are regularly performed in the United States and other parts of the world.    

Methods of Refractive Eye Surgery
The process of this type of surgery involves remodeling the cornea of the eye. The most common technique in use these days involves an excimer lasers for reshaping of the curvature of the cornea. Some of the common methods of refractive eye surgery include:

* Flap Procedures: A blade called microkeratome is used in these surgeries to cut a flap of corneal tissue. Lasik or Laser Assisted In-Situ Keratomileusis is the most common example of this procedure which uses an excimer laser to target the desired tissue.

* Surface Procedures: Some common surgeries performed under this method include Photrefractive Keratectomy (PRK) and Laser Assisted Sub-Epithelium Keratomileusis (LASEK). These surgeries also involve the use of laser, however they do not require making a cut into the stroma of the eye.
* Corneal Incision Procedures: Radial Keratotomy (RK) is an example of surgery using this method. In this method a diamond knife is used for correcting the shape of the cornea. This surgery is used to common problems of eye such as myopia and astigmatism are cured. However, this method is mostly being replaced by methods which use an excimer laser.

Precautions and Risks in Refractive Eye Surgery
It’s true that refractive eye surgery is a modern and efficient method of correcting vision defects, however it is not suitable for every one. If you are a victim of common diseases such as diabetes or glaucoma then the refractive surgery would not be suitable for you. You should also avoid this type of surgery if you are a pregnant or have certain eye diseases involving retina or cornea defects.

In this case, people who are planning to see an eye doctor for an eye exam should keep clear in mind the difference of the kinds of eye tests and what they can get from certain tests.

A focimetry exam is always conducted by the doctor to determine the current prescription strength if the patient is wearing eyeglasses. To ensure the stability of the prescription, the eye doctor is also likely to give refraction, which can also verify the current prescription. In detail, an auto-refraction will first be used to determine the baseline prescription. And a second light-based exam named slit lamp exam can examine the patient’s cornea, conjunctiva, lids, iris and lens using a microscope and a small beam.

For additional information, the patient can also receive an ocular muscle assessment, which can evaluate the strength and flexibility of the eye muscles. Moreover, a tonometry exam is sometimes carried out to measure the eye pressure, which always helps in diagnosing glaucoma. At the last, the internal eye may be tested through a retinal exam, in which case eye drops are needed.

Regular vision examination is only one of the services that are enabled by consulting a health professional for everything checks. These doctors’ visits are indispensable actions to maintain a healthy lifestyle, in addition to exercising, taking vitamins, eating healthily and refraining from smoking and so on.

This simple question is profound, because it touches on an invention that has changed the way in which the world views vision correction and has helped millions of people worldwide to see better without the aid of glasses or contact lenses.

For perhaps millions of years, much of human kind has suffered with vision problems. There are the serious eye diseases such as cataracts, glaucoma and a myriad of other problems. Beyond this is the simple fact that many people are unable to see clearly at distance, near, or both. This is from the imperfections of the eyeball as a camera and this was greatly helped over that last few hundred years by glasses and more recently in the last 50 years by contact lenses. Although with the advent of lasers, there was a hope that such technology could improve vision, limitations in the nature of the eye had limited laser application to vision correction until the advent of LASIK .

LASIK is a hybrid procedure, that is it involves two steps which together are able to improve vision very rapidly and predictably for patients with ametropias. The first step is to create a potential space for the laser to correct the vision and the second is to do the correction itself. In the early days of LASIK about 15-20 years ago , this potential space was made with a device called a microkeratome. This is a miniature shaver which can peel a thin layer of outer tissue from the cornea which remains attached at the edge or “hinge”. Another laser, the excimer laser then focuses on the freshly cut surface, and removes tissue in a programmed manner to reshape the eye. Finally, the flap is replaced which assumes the contour of the newly shaped cornea beneath it. It is the transfer of the shape combined with covering the treated area with living tissue that makes LASIK so remarkable. Healing occurs at the edge or seam of the flap and the eye barely knows that anything has occurred beneath. The vision is rapidly restored with no significant healing response, which is key to the success of LASIK.

Newer lasers, called femtosecond lasers, are able to make the flap layer more precisely without a cutting blade but fundamentally perform the same function. This all laser approach is a safer and slightly more effective way of restoring vision by LASIK. The current state of the art in LASIK is to use advanced femtosecond lasers such as our Visumax to make a flap, and a wavefront optimized excimer laser like our Zeiss or our Allegretto laser(s) to reshape the cornea. With this type of treatment we have a very low complication rate, and excellent vision results in most cases.

We become complacent very quickly with new technologies but it is a truly amazing and revolutionary accomplishment that in a procedure that lasts only a few minutes , a persons vision can be corrected from a lifetime of limitations.

Dr. Dishler is the first doctor to perform LASIK in Colorado, the first doctor to offer blade free LASIK in Colorado, and is a consultant, lecturer, and inventor. He is involved with several FDA studies and answers questions related to laser vision correction online.
