All-Laser LASIK (with IntraLase)
LASIK is an acronym for Laser-Assisted In Situ Keratomileusis – a procedure to reshape the cornea, reducing refractive errors such as nearsightedness, farsightedness and astigmatism. By reshaping the cornea, light is allowed to properly focus on the retina, helping you see better. This can thereby decrease or even eliminate people’s dependence on glasses or contact lenses. LASIK surgery involves two basic steps: creating a corneal flap, and then reshaping the cornea.
All-laser LASIK refers to procedures where the IntraLase laser is used for the first step of the procedure. Traditionally, doctors have performed this first step using a hand-held device with an oscillating metal blade, called a microkeratome. But now, we are able to create the corneal flap more precisely and accurately utilizing the IntraLase laser. This computer-controlled laser is less invasive and dramatically reduces the risk of complications during the LASIK procedure.

Advanced Surface Ablation (LASEK/PRK)
Although most people are candidates for LASIK enriched with IntraLase, some have corneas that are too thin for LASIK. Vision correction procedures can still be performed for these patients by treating the surface of the cornea, rather than by first creating a flap. Surface treatments can be described as Advanced Surface Ablation (ASA), and variations include LASEK and PRK. After surgery, most people experience more discomfort with Advanced Surface Ablation and have a longer visual recovery period compared to LASIK. Post-operative drugs must also be continued for a much longer period of time (several months) and protection from ultra-violet exposure is very important for approximately six months. Ultimately, the visual outcome is comparable to LASIK, which is usually excellent. We offer Advanced Surface Ablation for our patients that are better candidates for surface treatment than for LASIK.

Refractive Lens Exchange (RLE)
Refractive Lens Exchange is a non-laser corrective procedure in which the natural lens of the eye is removed and replaced with an artificial lens, called an intraocular lens (IOL), similar to cataract surgery. This procedure is for people with moderate to high degrees of nearsightedness or farsightedness. Refractive Lens Exchange is a permanent and maintenance-free vision correction option with a quick visual recovery time. The outcome of the surgery is predictable; plus, it eliminates the need for future cataract surgery and preserves the central cornea.
There are two basic types of IOLs available to use for Refractive Lens Exchange, a monofocal or a multifocal IOL. A monofocal IOL is designed to provide clear vision at only one depth, usually distance. A multifocal IOL is designed to provide a full range of vision, including distance and near. The ReSTOR IOL is a multifocal implant.
with ReSTOR® IOL
The ReSTOR multifocal IOL is designed to provide you with a full range of vision allowing you to see objects far away and up close. The ReSTOR IOL is ideal for people with nearsightedness or farsightedness in addition to presbyopia (loss of reading vision). This lens design allows for clear distance vision (watching children playing in the backyard), near vision (reading), and intermediate vision (computer work). You may therefore be more independent of glasses for daily tasks after having a Refractive Lens Exchange with the ReSTOR lens.

Phakic Intraocular Lens
A phakic intraocular lens can be used to treat a wide range nearsightedness and farsightedness. The procedure involves inserting an implant called an intraocular lens (IOL) into the eye’s anterior chamber (the area in front of the pupil), or into the posterior chamber (the area between the iris and the normal lens). The eye’s natural lens is left in place. The majority of patients achieve a significant increase in uncorrected visual acuity. The initial use of these implants will be for people that are too nearsighted for LASIK or have corneas that are too thin for LASIK.

Radial Keratotomy (RK)
Radial Keratotomy is a surgical procedure used to decrease nearsightedness. During the procedure, radial incisions are made in the cornea of the eye with a precise diamond blade set to a particular depth. The number of incisions and their location is determined by the degree of nearsightedness. These incisions allow the sides of the cornea to curve outward, flattening the central portion of the cornea. The result is that the focal point of the eye is closer to the retina, and distance vision is improved.

|
Astigmatic Keratotomy (AK)
Astigmatic Keratotomy is a surgical procedure that corrects astigmatism by making one or two incisions at the steepest part of the cornea. These incisions cause the cornea to relax and form a more rounded shape, thus improving uncorrected vision. This procedure is for people with a low degree of astigmatism.
|
back to top
|
Limbal Relaxing Incision (LRI)
Limbal relaxing incisions are a modification of astigmatic keratotomy (AK), a procedure to treat astigmatism. Incisions are placed on the far peripheral aspect of the cornea (the limbus), resulting in a more rounded cornea. Astigmatism is reduced, and uncorrected vision is improved. LRI can be performed either at the time of cataract surgery or as an independent procedure.

The Process & Our Technology
Experience the laser vision correction process, and learn about how our exciting technology can help you achieve better vision!
At the Eye Center of Central Georgia we utilize only the most advanced FDA-approved technology to help you attain your personal best vision.
|
WHAT TO EXPECT:
First, we need to determine if you are a candidate for laser vision correction or another type of refractive procedure. The simplest way to do this is at a complimentary consultation. You can come by the center to learn more about our refractive services, our technology, pricing and financing options, and whether or not you may be a candidate.
Next, we would need to do a pre-procedure evaluation. This is a comprehensive medical eye exam with one of our physicians. This step is critical to accurately measure your vision and to ensure that you are indeed a good candidate. By providing all-inclusive pre-operative diagnostics and planning, outcomes can be optimized to make certain you receive the best results possible
|

HOW IT WORKS:
PRE-PROCEDURE EVALUATION – We utilize the most advanced diagnostic equipment and techniques to determine candidacy for laser vision correction and to aid in planning for the treatment.
|
Step 1: WaveScan
VISX WaveScan technology is used to produce a detailed map of your eye - much like a fingerprint, no two are alike. The WaveScan device identifies and measures the unique imperfections in your vision that could not be measured and corrected before. WaveScan technology was originally developed for use in high-powered telescopes to reduce distortions when viewing distant objects in space. WaveScan measures 25 times more precisely than standard methods used for glasses and contact lenses.

|
Step 2: Orbscan IIz
We use the Orbscan corneal topographer to provide a detailed analysis of the cornea. This device is a highly sophisticated diagnostic system that scans the surface of the cornea to meticulously measure and analyze the elevation and curvature of your cornea. The Orbscan provides the doctor with information regarding the cornea including:
- Contour map of the surface
- Elevation map of the anterior surface
- Elevation map of the posterior surface
- Thickness map of the entire cornea
|
|
 |
Measurements by an Orbscan are critical to ensure the cornea will respond well to treatment. This should be used by any refractive surgeon during the pre-procedure stage of treatment.

Step 3: Procyon Pupillometer
The Procyon Pupillometer is used to measure your pupil size prior to refractive surgery. It can measure your pupil size in various lighting situations. The Procyon is the most accurate method of measuring the size of the pupil in dim light (the most common lighting situation at night). These measurements are used to aid in planning and settings the surgeon will use during the procedure.

Step 5: Comprehensive Medical Eye Exam
This exam includes multiple non-dilated and dilated refractions, exam of front and posterior segments of the eye, glaucoma testing, retinal examination, and a full medical and ophthalmic history. A truly comprehensive exam pre-operatively is key to a successful post-operative outcome.
|
 |
back to top
PROCEDURE – The diagnostic test results are then used to plan treatment. Our physicians carefully review all data to determine which procedure best fits your needs. We can proceed with surgery once all pre-operative data is acceptable.
|
Step 1: IntraLase
We use the IntraLase FS femtosecond laser to create the corneal flap for the first step in the LASIK procedure, rather than the traditional bladed instrument called a microkeratome. The computer-controlled IntraLase laser allows the surgeon to ensure a perfectly centered flap of predictable size, shape, and thickness and virtually eliminates all the risks associated with creation of the flap.
This device utilizes an infrared laser to create the corneal flap at a programmed depth and position. IntraLase is safer than a traditional mechanical microkeratome and provides better post-operative vision than microkeratomes. IntraLase provides a uniquely precise, uniquely safe, way to provide you with predictably better vision after your LASIK surgery.
|
|
|
|
|
Uniquely Precise:
- Centration of flap is much better than with microkeratome
- Diameter of flap is much more precise
- Thickness of flap is also much more precise
|
Uniquely Safe:
- No incomplete flaps
- No “free caps”
- No “button-holes”
- No abrasions
|
Predictably Better Vision:
- Better post-op vision than with microkeratomes
- Fewer enhancements
- Less dry eye
- More rapid healing
- Faster vision recovery

Step 2:VISX Star S4
The VISX Star S4 excimer laser is used to reshape the cornea during LASIK and Advanced Surface Ablation. The Star S4 is the most advanced excimer laser available today. VISX was the company that developed excimer laser technology for laser vision correction and gained clearance from the FDA for correcting a variety of vision conditions. VISX is recognized worldwide for bringing innovation and breakthrough technology to laser vision correction. The Star S4 laser system has several features worth noting:
|
|
|
|
 |
ActiveTrak® 3-D Eye Tracker The laser’s infrared cameras actively follow even the tiniest motions of your eye in all three dimensions. This allows you to relax during your treatment – knowing the procedure will be delivered accurately.
ActiveTrak Automatic Centering The doctor is able to precisely identify the center of your pupil with this feature, and able to keep the laser centered to within 50 microns (about the width of a human hair), even if your eye moves.
|
|
|
Variable Spot Scanning (VSS™) The laser incorporates a sophisticated array of seven beam diameters ranging from 0.65 to 6.5 millimeters to give you a personalized treatment quickly and efficiently. VSS gives the surgeon greater flexibility to personalize your laser vision correction with a larger treatment area.
Variable Repetition Rate (VRR) Variable repetition rates allow for faster treatments which lead to improved results. This is because the cornea dehydrates with time and a faster laser minimizes dehydration which translates into more accurate treatments.
Direct Transfer of Digital Information With the VISX CustomVue procedure, we are able to save data from the WaveScan and then transfer that data directly to the Star S4 laser to guide treatment.

Liebert Climate Control System
Temperature and humidity in any refractive center need to be controlled for optimum outcomes. In our refractive suite, we utilize the Liebert Climate Control System, a complex system which monitors and controls temperature and humidity levels throughout the room. This system ensures that the suite’s environment is suitable for the lasers to safely and accurately perform procedures.
|
| |
|
You want to be sure that the surgeon and center you choose utilize all of the above mentioned advanced technologies for laser vision correction; if not, you may need to rethink your choice of surgeon.
