Laser Eye Surgery Options for Patients with Thin Corneas

Updated: Jul 14

Refractive issues are among the common concerns of vision correction which need to be addressed in a timely manner. To begin with, the degree of refractive error is examined by the doctor in order to determine corneal thickness. Based on the thickness, the patient's eligibility for Lasik is evaluated by the ophthalmologist. But, there are many people who have thin corneas which implies that these individuals do not prove to be good candidates for Lasik surgery. If you are planning to seek assistance for laser eye surgery in Delhi, then, read on to explore various aspects about thin cornea and their impact in vision correction.

Factors involved in determining eligibility for Laser eye Surgery

The doctor initially conducts tests to assess corneal thickness, considers age, degree of refractive error and thereby, evaluates whether you are eligible for the laser eye surgery or not. In this process, corneal topography to understand the thin structure of cornea gets identified by the ophthalmologist. If you have corneal thickness less than 485 microns, then, thin cornea case is taken into consideration at the eye care clinic. In addition, treatment suitability is also a major influencing factor that plays a vital role in estimating the patient’s eligibility for refractive procedures.

Implication of thin corneas in vision correction

The transparent tissue in the outermost layer of the eye that protects eyes from dirt and germ is known as cornea. It further filters out the UV rays of light and the normal thickness of cornea is 540 microns. But, when this thickness level decreases than 500 microns, the corneas are considered to be thin. In the context of Lasik surgery, if patients with thin corneas undergo this eye surgery, the substantially weakened eyes can be witnessed. In the worst cases, the procedure can also lead to permanent blindness.

Coping up with laser eye surgery options for thin corneas

Since the extent of refractive error is analyzed before understanding the treatment to be proceeded with by the surgeon, the first step is to gather evidence for the suitability for laser eye surgery. Apart from this, the lifestyle factors, pre-existing corneal disease and suitability of candidates with thin corneas are some of the important considerations that enable the doctor to finalize the right option for best laser eye surgery. Here are some of the options which can be used for thin cornea eye treatment:

1. Lasik surgery

This eye surgery involves the creation of flaps using the cornea tissue to address vision correction issues. As a part of this procedure, the amount of tissue gets reduced when reshaping of cornea is carried out. The Lasik eye surgery cost in India is also quite affordable.

2. Surface Ablation

In this eye surgery, epithelium or the topmost layer of the cornea is removed to treat refractive errors further correcting the vision. If you have been planning to attain spectacle free vision through eye surgery with thin corneas, then, the surgeon ensures no flap is created during the procedure while maintaining safety. On the other hand, to protect the cornea, the doctor inserts bandage contact lenses to protect the cornea until the healing or growth of the epithelial layer. The discomfort within the eye is reduced with the thick contact lens inserted in the eye.

3. Wave-front guided Lasik

In this procedure, computerized imaging technology is utilized to create a 3D map of your cornea to assess the implication of using excimer laser for reshaping the cornea. With the help of wave-front guided Lasik, abnormalities of the corneal surface are identified. It is one of the safer and effective laser eye surgery options for patients with thin corneas.

4. Contoura vision topography guided Lasik

On the basis of eye’s shape, the vision correction plan is chalked out by the ophthalmologist in this US FDA approved eye surgery. Over 22,000 points of the eye are measured as a part of this treatment to attain improved visual acuity in a safe manner.

5. Intraocular lenses

These implantable contact lenses or ICL relies on the utilization of artificial lenses which have been prepared with the biosynthetic materials. These lenses are inserted between the iris and crystalline lens and only a small incision is made to position the ICL in the eye. The outcome of getting these lenses inserted in the eyes is that a high degree of myopia, astigmatism and hyperopia can be treated which cannot be attained in Lasik eye surgery or PRK procedure.

6. Refractive lens exchange

This procedure of vision correction is similar to cataract surgery, wherein, the crystalline lens is still clear unlike the case of cataract. The corneal tissue is not removed by the doctor in refractive lens exchange just like ICL procedure. Moreover, if you have passed the age of presbyopia or attained age related vision issue, then, this laser eye surgery will be perfectly applicable in your case.
