To achieve visual clarity without the need for glasses or contact lenses, various laser eye surgeries have emerged as effective solutions. One such procedure gaining popularity is LASEK eye surgery. In this article, we will discuss LASEK – what it is, the procedure involved, its benefits, associated costs, and more.
What Is LASEK?
LASEK, or Laser Epithelial Keratomileusis, is a laser eye surgery procedure designed to correct refractive errors, providing individuals with clearer vision and reducing or eliminating the need for glasses or contact lenses. It is considered an alternative to other laser eye surgeries, such as LASIK, and is chosen based on individual patient characteristics.
What Is It For?
LASEK eye surgery is primarily performed to correct refractive errors. Refractive errors occur when the cornea (the clear front part of the eye) does not properly focus light onto the retina, leading to blurred or distorted vision.
Some refractive errors that LASEK can address include:
- Nearsightedness (Myopia).
- Farsightedness (Hyperopia).
- Astigmatism.
Who Are The Suitable Candidates?
Those with thin corneas, dry eyes, or occupations with a higher risk of eye trauma may find LASEK to be a more suitable option than other laser eye surgeries such as LASIK.
Candidates should also have stable vision for at least one year, be in good overall health, and have realistic expectations about the outcomes of the surgery.
Is It Safe?
It is considered a safe and effective procedure for eligible candidates. As with any surgical intervention, there are potential risks and complications, but the majority of patients experience significant improvement in their vision with minimal side effects.
What Does The Procedure Involve?
The procedure is typically done with anaesthesia applied onto the eyes. During the procedure, an alcohol solution will be applied to loosen the outer layer of the cornea (epithelium). Once loosened, the surgeon gently moves this layer aside to expose the underlying corneal tissue. The laser is then used to reshape the cornea based on the patient’s specific refractive error. Finally, the epithelial layer is repositioned to facilitate natural healing.
What Is Its Main Difference With LASIK Eye Surgery?
Unlike LASIK, LASEK involves preserving a thin layer of the cornea’s surface (epithelial tissue) during the procedure.
What Should You Expect Before The Procedure
Before undergoing LASEK, patients may expect a comprehensive eye examination to determine their eligibility for the procedure. The surgeon will discuss the potential risks and benefits, address any concerns, and provide pre-operative instructions, which may include discontinuing contact lens wear for a specified period before the surgery.
What Should You Expect After The Procedure
Following the procedure, patients may experience some discomfort, mild pain, and blurred vision for a few days. The surgeon may prescribe medications to alleviate any discomfort and promote healing. It is crucial for patients to follow post-operative care instructions diligently and attend scheduled follow-up appointments.
How Long Is The Recovery Period?
The recovery period for LASEK is longer compared to LASIK. Recovery of functional vision may take up to two weeks.
Are There Risks?
While the procedure is generally safe, like any medical procedure, it carries some risks. These can include:
- Dry Eyes
- Halos or glare, especially in low light conditions.
- Infection.
- Changes in vision.
It is to note that serious complications are rare, and the majority of patients experience significant improvements in vision.
How Much Does It Cost?
In Singapore, it may cost S$3,600 and above. It is important to note that the cost may vary depending on the clinic chosen, surgeon, other fees, and other factors.
