Clear vision which most people only notice when it is affected by glasses, contact lens, or by blurred eyesight. Tasks like reading a phone screen, driving at night, using a laptop, or recognizing a face from a distance become difficult when the eye does not focus light correctly. For many patients Refractive Surgery presents a solution to reduce dependence on glasses or contact lenses by fixing the eye’s focusing defect.
At ASG Eye Care we see that many of our patients question if these procedures are only for those with a high degree of correction or if they are an option for anyone wearing glasses. The answer is that it depends on the patient’s age, prescription stability, corneal thickness, eye health, and what they expect. Laser Vision Correction has come a long way over the years but at the same time the best treatment should always be determined after a full eye evaluation. Through Refractive Surgery we aim not only at improving vision but also at providing long term visual comfort, safety, and confidence.
What Is Refractive Surgery?
Refractive Surgery is a group of eye based procedures that correct what is known as refractive errors which include myopia, hyperopia, and astigmatism. These errors which are a result of the eye’s improper focus of light cause the image to focus in front of, behind, or unevenly on the retina. This in turn causes blurred vision at distance, near, or both.
In many cases the procedure consists of changing the cornea to the clear front of the eye. When the cornea is reformed precisely light enters the eye better focused, which in turn causes the patient to see more clearly which in some cases does away with heavy use of glasses or contacts. Also some of these procedures put in a special lens within the eye instead of changing corneal shape.
Refractive Surgery is not for all eye issues. It does what it is supposed to do, which is to correct focus, not to treat issues like cataract, glaucoma, diabetic retinopathy, or retina disease. That is why we do very thorough screening before surgery. We aim in refractive surgery to put the right patient in the right procedure so that the result is safe, stable and relevant to the real world.
Who Can Consider Refractive Surgery?
Not all patients are good candidates for Refractive Surgery. We usually consider a patient a good fit for Refractive Surgery when the power of the eye has been stable for what we consider to be a reasonable time which we define as at least a year. Also the patient should have healthy corneas, sufficient corneal thickness, controlled dry eye, and no active eye infection or uncontrolled systemic disease.
Age is also a factor. We see that for the most part procedures are put off until adult years when the patient’s eye power has stabilized. Also we have patients with very thin corneas, irregular cornea shape, advanced dry eye, keratoconus, uncontrolled diabetes, pregnancy related changes in prescription, or just plain unrealistic expectations which do not make good candidates. In these cases the ophthalmologist may recommend waiting, a first course of medical treatment, or a different vision correction option.
At ASG Eye Care we do not base our decisions on what the glasses prescription says. Our surgeon does corneal mapping, measures pupil size, tests tear film quality, assesses retina health and looks at the overall eye condition before putting forth any treatment plan.
Common Types of Refractive Surgery
Today there are a variety of procedures which we have at our disposal and each is different in what it does. In Terms of Types of Refractive Surgery what we see is that they range which is to say that for one person we may recommend LASIK and for another PRK, Contoura, or ICL.
| Procedure | How it works | Commonly suitable for |
| LASIK Surgery | A thin corneal flap is created, and an excimer laser reshapes the cornea underneath. | Patients with stable power, good corneal thickness, and healthy eye surface. |
| Femto LASIK | A femtosecond laser creates the corneal flap instead of a blade, followed by laser reshaping. | Patients seeking bladeless flap creation and improved precision. |
| Contoura Vision | A topography-guided laser treatment corrects prescription along with subtle corneal irregularities. | Patients suitable for customized corneal correction. |
| PRK Surgery | The surface layer of the cornea is removed, and the laser reshapes the cornea without creating a flap. | Patients with thinner corneas or those not suitable for flap-based LASIK. |
| SMILE | A small lenticule is created inside the cornea and removed through a tiny incision. | Selected patients with myopia and suitable corneal parameters. |
| ICL Surgery | A special implantable lens is placed inside the eye without removing corneal tissue. | Patients with high power or corneas unsuitable for laser-based correction. |
The proper Types of Refractive Surgery are chosen after in depth evaluation. One procedure does not necessarily do better than the other. What is best is what fits the patient’s eye structure, prescription, occupation, lifestyle, and long term safety.
How the Procedure Works
In the beginning of the process we have a very in depth pre op consultation. The eye doctor measures the patients’ glasses power, does a corneal topography or tomography, looks at the corneal thickness, does study of the tear film, and also looks at the retina. These tests are to determine if the patient is a good candidate for Refractive Surgery and which procedure is the safest.
In the LASIK Surgery process we use an anesthetic for the eyes prior to the procedure. We create a corneal flap which we then reshape the cornea with a laser as per the treatment plan, after which the flap is put back in place. The procedure is usually fast and it is very common for patients to see an improvement in their vision very soon.
In PRK Surgery, which does not create a corneal flap, what happens is the surface layer of the cornea is very gently removed and the laser is applied to the surface. Also it takes a little longer to heal as a process as compared to LASIK but this may be a very good option we have for patients that are not good candidates for flap based procedures.
In ICL Surgery, which is a type of eye surgery the doctor puts in a very thin biocompatible lens within the eye. This we see as a solution for patients which has high spectacle power or does not have enough corneal thickness for laser procedures. The natural lens which is inside the eye is left as it is and also the cornea is not re-shaped.
Through Contoura Vision we tailor the treatment which is based on in depth corneal mapping. This allows the laser to correct not only spectacle power but also some corneal surface irregularities which in turn improve visual quality.
Benefits of Refractive Surgery
Refractive Surgery’s greatest benefit is that it reduces the need for glasses or contact lenses. Many patients report feeling more at ease with daily activities, sports, travel, professional work, and social situations post treatment. For those that have issues with contact lenses’ comfort or find glasses to be an issue, this is a very meaningful improvement.
Another key benefit is visual freedom. Patients report that they wake up to better vision, have the ability to exercise without glasses which sometimes fall out, and also that they no longer have to clean or replace contact lenses. For some patients Refractive Surgery is a very stable and satisfactory solution in the long term.
However at the same time it is important to note that the procedure is not at all cosmetic. Clear sight impacts quality of life, safety, confidence and daily performance. When carried out after proper evaluation Refractive Surgery may be a life improving procedure for the right patient.
Possible Risks and Limitations
In the same way that all medical procedures do, Refractive Surgery does present with risk. Most do very well out of it but some may have issues like dry eyes, glare at night, halos around lights, light sensitivity, fluctuating vision, and in general a bit of pain as the wound heals. The issues which do come up usually fade away with the passage of time and proper post op care.
A few patients do have under and over correction as well as regression which at times sees some power return. Also we see at times infection, inflammation, flap issues, or corneal weakening. That is why pre op screening and surgeon experience is very important.
The procedure also reports that it doesn’t stop age related changes which for instance see people in their 20’s and 30’s who have Refractive Surgery they may still end up with presbyopia which forces them into reading glasses. Also age will still see some develop cataracts which may require separate treatment.
Recovery After Refractive Surgery
The procedure also reports that it doesn’t stop age related changes which for instance see people in their 20’s and 30’s who have Refractive Surgery they may still end up with presbyopia which forces them into reading glasses. Also age will still see some develop cataracts which may require separate treatment.
| Recovery point | What patients can usually expect |
| First few hours | Mild watering, irritation, light sensitivity, or foreign-body sensation may occur. |
| First 24–48 hours | Vision often improves, especially after LASIK-based procedures. |
| First week | Dryness, mild glare, or fluctuating vision may be present and managed with prescribed drops. |
| First month | Vision becomes more stable, and most routine activities are comfortable. |
| Long-term follow-up | The doctor checks corneal health, vision stability, dryness, and overall healing. |
After having the refractive surgery patients should stay away from eye rub, swimming, eye make up, dusty settings, and self medicating during the early healing stage. Eye drops should be used as prescribed. Also it is important to keep follow up visits as during the process of healing your eye may feel fine before it is fully stable.
How to Choose the Right Procedure
Choosing which procedure is not based on what is the most popular or the most expensive. It is what is best and safest for the patient’s eyes. We see that a person with adequate corneal thickness may be a good candidate for LASIK, while someone with thinner corneas may do better with PRK. A patient with high power may see greater results from ICL than from corneal laser procedures.
Patients also need to look at lifestyle issues. For a person in contact sports, defense work, or very physical activities we may take a different approach from that of a desk worker. Also note night driving, screen time, dry eye issues, and future eye health issues.

Refractive Surgery at ASG Eye Care
At ASG Eye Care we take a patient first approach to Refractive Surgery. We do a in depth eye evaluation which includes corneal scans, dry eye assessment, prescription stability check, and full eye exam. We do this to make sure the procedure is safe for your eyes before we determine it is a good fit.
The team goes over your options which include LASIK Surgery, Contoura Vision, PRK, SMILE, and implantable lens based procedures. We take you through what to expect before, during, and after the procedure. This helps reduce anxiety and improve confidence in the treatment plan.
ASG Eye Hospital also has a focus on follow up care. Immediate recovery is a thing of the past the day of surgery. We do routine eye drop prescriptions, healing check ups, dry eye management and visual acuity assessments as part of our responsible care. With right patient selection and post op care Refractive Surgery can do for many patients what is to have better vision and greater daily comfort.
Key Takeaway
Refractive Surgery may decrease one’s dependence on glasses or contact lenses as it corrects how the eye focuses light. This form of surgery has many types including but not limited to LASIK, PRK, Contoura, SMILE, and ICL, each of which is designed for particular eye issues and patient needs. For best results it is best to select the right procedure after a detailed eye exam.
Patients note that Refractive Surgery is not for all, also it does not stop age related eye changes. But for the right patient, with the right technology and expert care, it can be a safe, effective, and life improving vision correction option.
Frequently Asked Questions
1 What is Refractive Surgery?
Refractive Surgery which is a set of procedures that correct myopia, hyperopia and astigmatism. What it does is to reshape the cornea and also in some cases put in a special lens which improves how light focuses on the retina.
2 Is Refractive Surgery Safe?
Refractive surgery in general is a safe option for proper candidates when performed by an experienced ophthalmologist with the right technology. But as with any procedure there is a chance of complications which include dry eye, glare, halos, fluctuating vision, infection, or under correction which we discuss in detail at the consultation.
3 Who is not suitable for Laser Vision Correction?
Patients which have unstable eye pressure, very thin corneas, keratoconus, active eye infection, severe dry eye, uncontrolled diabetes, pregnancy related prescription changes, or certain retinal conditions may not be suitable. A full eye exam is required before making a decision.
4 How long does recovery take?
Recovery time varies by procedure. For LASIK based treatments improvement is often seen within a day or two, but with PRK we see a slower response as the eye’s surface has to heal. Full stabilization may take a few weeks, which also will vary based on the individual patient and the type of treatment they have.
5 Is the result permanent?
During the course of laser based treatments which is what causes the corneal reshaping that is a permanent change. But for some patients which may include that which comes with age like presbyopia or development of cataracts which may still present itself at a later date. This in turn may require the use of reading glasses or other eye care in the future.
6 Which procedure is best for me?
There isn’t a single best procedure for all. What works best for you will depend on your prescription, corneal thickness, corneal shape, age, dryness level, lifestyle, and over eye health. Your eye specialist will do in depth tests to put forth the best option for you.
