This procedure involves first creating a thin flap of the cornea with an instrument called the microkeratome. Followed by the lifting of the flap and laser treatment to reshape the cornea. The flap is then repositioned in its original place. Improvement in vision is noted right from the next day.
The beam profile of Wave light laser has been wavefront-optimized, hence it removes a lesser amount of corneal tissue when compared to other laser machines, thus making the treatment safer for your eyes. Wavefront optimization also ensures that you do not experience any.
Glare or halos during the night while looking at bright lights. Wavelight laser allows multiple options for customized treatments, such as wavefront-guided, topography-guided, Q factor guided treatments. Such treatment modalities are far superior when compared to those with other lasers such as zyoptix, custom vue, or custom cornea
Both PRK and LASIK procedures are absolutely painless and are performed as an outpatient procedure using topical anaesthetic eye drops. The entire procedure lasts for only 10 -15 minutes and you will be awake during the entire procedure. During the treatment, you are required to look at a fixation light while the laser is performed and you will also hear the noise of the laser machine during the treatment. The actual laser treatment only lasts for 15 to 45 seconds. Following the treatment, you can return home immediately. However, you should make arrangements for a friend or relative to take you home after the procedure.
After going through our site there will be many doubts rising in your mind. We have tried to answer a few general questions for more details you can contact us we will be more than happy to be of assistance to you.
- Am I eligible for LASIK?
- While most patients are eligible for LASIK, not everyone is.
- An ideal candidate for refractive surgery?
- Must be at least 18 years of age with stable refraction for 1 year.
- No associated eye diseases.
- No connective tissue disorders.
- Must discontinue contact lens wear 2 weeks prior to refractive surgery.
Eligibility also depends on the number of refractive errors, the curvature and thickness of the cornea and a number of other factors that an ophthalmologist must evaluate. Proper patient selection is vital for successful refractive surgery and a satisfied patient.
Will my vision improve immediately?
There is a considerable improvement in unaided vision following the treatment. Following PRK the vision improves 3-4 days later once the surface healing incomplete. Following LASIK this improvement is noted right from the next day. However, a slight fluctuation of vision may occur over the next few months as the healing process continues.
What are the possible side effects?
Usually, most patients are quite comfortable following LASIK. There is a moderate amount of pain following PRK on day 1, which reduces subsequently. There may be transient light sensitivity, glare & foreign body sensation, or dryness in the treated eye. Sometimes there may be a slight under correction or over correction following the procedure.
Will I need to wear glasses or contact lenses after the procedure?
Both PRK and LASIK are designed to allow you to discontinue the use of corrective lenses for routine daily work. In some patients with higher refractive errors, corrective lenses of lower power may still be required following the treatment. In some individuals, this residual refractive error can be corrected by a second refractive procedure
When can I resume normal activities?
You can return to work after 3 days if PRK has been performed. Following LASIK you can return to work the following day. While most activities can be resumed, it is better to avoid swimming, contact sports etc at least for a one-month duration.
Are the results of LASIK permanent?
LASIK permanently removes corneal tissue to reshape the eye in order to improve refraction. The physical results are permanent. However, you should be aware that since the eyes can still change with time, LASIK does not prevent presbyopia or affect this condition once it does occur.
Should I undergo LASIK?
Ophthalmologists all over the world have been reshaping the cornea using the excimer laser since the 1980s. LASIK has been performed internationally for approximately 10 years now. While refractive surgery does not promise perfect vision, it does hold the promise of reducing one’s dependence on contacts or glasses. For many people, the reduction will allow them to more freely pursue their hobbies, sports activities or career options.
Refractive Procedure for Presbyopic Correction
Imagine you wake up to clear view of the world. Imagine you are set free from depending on Glasses and
Contact Lenses. Imagine you can see the world as sharp and clear from the time you wake up to the time you go to bed.
Conductive Keratoplasty (CK) or Near Vision CK is the preferred choice for Refractive Surgery by all the eye surgeons for patients above 40 years of age. It is done to correct Presbyopia by reshaping the cornea with the help of Radio Frequency energy instead of a Laser or Scalpel.
What is Presbyopia?
As we age, our eyes lose their ability to focus on near points. Reading, seeing the time on a watch, identifying the object near you or working on a computer becomes difficult. This usually begins to occur when we cross 40 years of age. It happens to everyone. Besides Reading Glasses, Conductive Keratoplasty is the only treatment available to correct Presbyopia.
Near Vision CK procedure is specifically for people over 40 years of age, who want freedom from Reading Glasses or Contact Lenses.
When a patient has gone through a LASIK Surgery or has implanted multi-focal / accommodating Intra Ocular Lenses (IOLs) during Cataract Surgery and still requires Reading and Distance Glasses, then CK treatment can be rendered to cure the problem.
The procedure takes only a few minutes
It is a safe and minimally invasive procedure which done without cutting and removing of eye tissues.
CK is the first US Food and Drug Administration (FDA) approved vision technology for patients with Aging Eyes i.e. Presbyopia.
CK is certified by the US Federal Aviation Administration (FAA) as a vision correction procedure for Pilots who want to reduce/eliminate their dependency on Glasses or Contact Lenses.
CK is the only safest and most effective procedure to obtain an FAA protocol for Refractive error correction.
Good Candidacy For Near VIsion CK
- You are a good candidate for Near Vision CK if you are tired of your Reading Glasses
- Have difficulty in reading the newspaper or identifying other objects which are close to you.
- Are at least 40 years of age
- Have had good distance vision for most of your life
- Have no health issues affecting your eyes
- Are not pregnant or nursing.
FDA Approved Equipment For CK
The Procedure is done with the help of ViewPoint CK System (from Refractec) which uses the probe with a Microthin (90u diameter) single-use KERATOPLAST tip for delivering Radio Frequency energy directly to the corneal stroma.
RF is one of today’s most advanced surgical technologies. In addition to its use in CK, RF technology is being used in prostate cancer therapy, back surgery and even cardiovascular procedures.
Your eyes will be examined using equipment as unique as the Wavefront technology itself. To assist our doctor please do not wear soft/rigid Contact Lenses for a minimum period of two weeks beforehand, as they distort the cornea and might influence the outcome of the treatment.
If you have any old prescriptions for Contact Lenses or Glasses or details of any eye treatment you have altered over time, we can best determine how to treat them.
STEP-I: Topical or Eye Drop anaesthesia is applied to numb the eye and to ensure a painless procedure.
STEP-II: A circular treatment pattern is imprinted on the cornea using rinse away the ink to guide the doctor’s treatment.
STEP-III: Using a probe, which is thinner than the strand of human hair, Radio waves are applied in a circular pattern to shrink a small area of collagen in the cornea.
STEP-IV: The circular treatment patterns will act like a belt-tightening around the cornea by increasing its overall curvature to improve near vision.
After The Procedure
Before you go home, our staff will give you personalized aftercare instructions and eye drops.
After the procedure, you will experience watering of the eyes for a certain time. This is a natural process, but please do not rub your eyes.
Follow Up Care
After the surgery, we recommend you see us as advised. This way you can help us properly monitor the success of your treatment.
Ck After Cataract Surgery
CK is the most attractive alternative for low postoperative hyperopia in a Cataract patient after Multi-focal or accommodating IOLs implantation. It is less invasive and traumatic than bringing patients back for another Intraocular procedure.
Ck After Lasik Surgery
It is also an alternative for over and under corrections following LASIK surgery or other excimer Laser treatment. 98% of Patients could see J5 (magazine-and newspaper-size print) in the eye that was treated by Near Vision CK. 87% of patients could see 20/20 in the distance and also read phone book-size prints (significantly smaller than newsprint)
There are NO reported serious, sight-threatening or unanticipated safety events.
Frequently Asked Questions
Is Conductive Keratoplasty (CK) permanent?
Conductive Keratoplasty is for the temporary reduction of farsightedness. No matter what type of procedure is performed, our eyes inevitably change as we age. Conductive Keratoplasty SM (CK) can turn back the clock on farsightedness.
Will my vision improve immediately after surgery?
Is Radiofrequency (RF) energy safe for use on the eye?
Yes, the use of RF energy is one of today’s most advanced surgical techniques
Will my vision fluctuate after the procedure is performed?
Most patients will experience mild fluctuation in their vision after surgery, but many will never notice it. Any fluctuation will usually subside within a few days.
Are both eyes corrected on the same day?
Will I have to wear patches over my eyes after the procedure?
What will I feel during the Near Vision CK procedure?
The Near Vision CK procedure is considered painless. You will be aware of support (speculum) which helps to hold and keep your eye open. The most common sensation which a patient experiences is a feeling of pressure on the eye only for a few seconds.
How soon will I be able to return to work?
With CK, the majority of patients are able to return to work and other normal activities on the day of their procedure. Although recovery is fairly quick, it is advisable to be careful with your eyes and avoid any overstrain for a couple of days.
Can Conductive Keratoplasty (CK) be financed?
Because Conductive Keratoplasty is elective surgery (Cosmetic), most health insurance plans do not cover it.
