Is SMILE Surgery Suitable for Individuals with Thin Corneas?

Responsive image

For those looking to reduce their dependence on glasses or contacts, refractive surgery can be a great option. However, not all procedures are good for everyone, especially for those people with thin corneas. SMILE surgery is a modern alternative to LASIK that is quickly replacing them due to its fine cutting edge and minimal ablation of corneal tissue. However, is it appropriate for patients with thin corneas? It is now time to look at how SMILE sits in terms of other refractive surgeries and whether it is viable for people with this situation.

What Is SMILE Surgery?

SMILE stands for Small Incision Lenticule Extraction – it is a modern type of laser vision correction. While in LASIK a flap is being formed in the cornea,SMILE surgery uses a laser to create and remove a small, lens-shaped piece of tissue (called a lenticule) of tissue through an entrance point. This makes it a less invasive procedure with shorter recovery periods and less effect on the overall corneal architecture.

The Challenge of Thin Corneas

Why Are Thin Corneas a Concern?

Thin corneas present difficulties for other refractive surgeries such as LASIK because the surgery requires some corneal tissue to be removed to alter the shape of the eye. Excessive tissue removal weakens the cornea and may lead to ectasia, which is bulging of the cornea, causing distorted vision

Measuring Corneal Thickness

Before any refractive surgery is suggested, professionals use diagnostic tools to assess the corneal thickness. The candidates who have corneal thickness less than 500 microns should undergo other procedures matching their case.

Is SMILE Suitable for Thin Corneas?

Differences between the corneal thickness are the primary reason why SMILE surgery is considered more suitable for people with slightly thinner corneas than in LASIK surgery. Here’s why:

1. Tissue-Sparing Procedure

Because SMILE removes less corneal tissue than LASIK, it's often a safer option for individuals with thin corneas. This approach helps to maintain the structural integrity of the cornea, which is particularly crucial for those with thinner corneas.

2. No Flap Creation

SMILE is an advantage over LASIK because it does not involve the formation of a flap in the cornea, because thin corneas are already more susceptible to weakness, avoiding flap creation is a significant advantage.

3. Reduced Risk of Dry Eyes

Unlike other surgeries like LASIK, SMILE surgery is less invasive and interferes with the corneal nerves to a smaller extent, thus minimizing dry eye syndrome after the surgery. This is especially beneficial for patients with thin corneas, as dry eye can further compromise corneal health.

4. Faster Recovery

SMILE patients usually get to recover much faster and can go back to doing their normal activities soon after the surgery.

Alternatives to SMILE for Thin Corneas

 

That said, SMILE is a perfectly acceptable option for some patients who may still require other forms of treatment. Here are a few options:

1. PRK (Photorefractive Keratectomy)

PRK is a type of laser eye surgery that modifies the cornea without having to make a flap. For the patients with thin corneas, it’s more suitable, but the healing time is longer than SMILE.

2. ICL (Implantable Collamer Lens)

ICL is an implantation of a lens in the eye without having to change the corneal shape. This procedure is suitable for people who have thin corneas, and those with high refractive errors.

3. Corneal Cross-Linking

Corneal cross-linking strengthens the cornea, making it more stable and potentially suitable for future refractive procedures in select cases. In such patients as those with keratoconus corneal cross linking can improve the corneal status.

Smile Beyond LASIK: Advanced Care for Every Patient

While LASIK remains one of the most popular vision-correcting surgeries, SMILE offers advantages for some patients. The least invasive technique implemented SMILE has been touted as the go-to alternative of Smile Beyond LASIK paired with the brief recovery phase which follows.

Thus, SMILE surgery is safer and more effective than other refractive surgeries for those with thin corneas. However, the suitability of all the methods is always determined by a doctor, based on a detailed eye examination. In offer to decide the best stage, in the event that you are situated at Coimbatore and hold the SMILE or LASIK, it is essential to counsel an eye clinic in Coimbatore. A visit to an eye hospital in Coimbatore to consult an ophthalmologist is the first step towards smoorth vision without risking the eyes.
