Understanding Vision Correction Surgeries

Before diving into the specifics of each surgery, it's important to understand the common goal: to reshape the cornea, which is the clear front part of the eye. This reshaping allows light entering the eye to be properly focused onto the retina, resulting in clearer vision.

LASIK (Laser-Assisted In Situ Keratomileusis)

How It Works
LASIK is the most well-known eye surgery. It involves creating a thin flap in the cornea, lifting the flap, and then using an excimer laser to reshape the underlying corneal tissue. The flap is then placed back in its original position, where it heals naturally. For those interested in corrective eye surgery treatment costs in Noida, it's important to note that prices can vary based on the clinic, the surgeon's expertise, and the specific technology used. 


  • Quick Recovery: Most patients notice improved vision within 24 hours.
  • Minimal Pain: The procedure is relatively painless, with only mild discomfort during healing.
  • High Success Rate: LASIK has a long track record of success with a high satisfaction rate.


  • Flap Complications: Though rare, issues with the corneal flap can occur.
  • Dry Eyes: Some patients experience dry eyes after surgery, which can be temporary or, in rare cases, long-term.
  • Not Suitable for Everyone: Patients with thin corneas or certain medical conditions may not be eligible.

SMILE (Small Incision Lenticule Extraction) 

How It Works
SMILE is a minimally invasive procedure. It involves creating a small, lens-shaped piece of tissue (called a lenticule) within the cornea using a femtosecond laser. This lenticule is then removed through a tiny incision, reshaping the cornea and correcting vision. 


  • No Flap: Since SMILE does not involve creating a flap, it reduces the risk of flap-related complications.
  • Less Dry Eye: SMILE tends to cause less dry eye compared to LASIK.
  • Stable Cornea: The corneal structure remains more stable, which is beneficial for patients with higher degrees of myopia (nearsightedness). 


  • Longer Visual Recovery: It may take a bit longer for vision to fully stabilize compared to LASIK.
  • Less Suitable for Hyperopia: SMILE is currently more effective for treating myopia than hyperopia (farsightedness).


How It Works
ProSMILE, a variation of SMILE, uses advanced technology to further refine the process. The technique and benefits are similar to SMILE, with enhancements in precision and patient comfort. 


  • Precision: Offers even greater accuracy in corneal reshaping.
  • Comfort: Improved patient comfort during and after the procedure.
  • Quick Recovery: Comparable to LASIK in terms of recovery time. 


  • Availability: ProSMILE is a newer technology and may not be available at all clinics.
  • Cost: It can be more expensive than standard SMILE or LASIK.

Clear Lens Extraction (Clear) 

How It Works
Clear Lens Extraction, also known as Refractive Lens Exchange (RLE), involves removing the eye’s natural lens and replacing it with an artificial intraocular lens (IOL). This procedure is similar to Cataract Surgery


  • Versatility: Effective for a wide range of vision problems, including presbyopia in Top presbyopia Hospital in Noida(age-related farsightedness).
  • Permanent Solution: Since the natural lens is replaced, it can prevent the development of cataracts in the future.
  • Suitable for High Prescriptions: Ideal for patients with very high prescriptions who may not be candidates for LASIK or SMILE. 


  • Invasive: It is a more invasive procedure compared to LASIK and SMILE.
  • Longer Recovery: The recovery period is typically longer.
  • Higher Risk of Complications: As with any invasive surgery, there is a higher risk of complications, including infection and retinal detachment.

Choosing the Right Surgery 

Factors to Consider
When deciding which eye surgery is best for you, consider the following factors:

1. Eye Condition: Your specific vision problem (myopia, hyperopia, astigmatism, presbyopia) will influence the best procedure for you.
2. Corneal Thickness: LASIK requires a certain corneal thickness, while SMILE and Clear can be options for those with thinner corneas.
3. Age: Clear is often preferred for older patients, particularly those with presbyopia in Top presbyopia Hospital in Noida
4. Lifestyle: Active individuals or those in contact sports may prefer SMILE or ProSMILE due to the lack of a corneal flap.
5. Recovery Time: If quick recovery is a priority, LASIK or ProSMILE might be more appealing.
6. Cost: Budget considerations can also play a significant role in your decision.

1. What is LASIK surgery?
LASIK (Laser-Assisted In Situ Keratomileusis) is a popular eye surgery that involves creating a flap in the cornea, reshaping the underlying tissue with a laser, and then repositioning the flap. This reshaping allows light to be properly focused onto the retina, resulting in clearer vision.

2. What is SMILE surgery?
SMILE (Small Incision Lenticule Extraction) is a minimally invasive procedure where a small, lens-shaped piece of tissue (lenticule) is created within the cornea using a femtosecond laser and then removed through a tiny incision. This reshaping of the cornea corrects vision issues.

3. What is ProSMILE surgery?
ProSMILE is an advanced variation of SMILE that uses enhanced technology for greater precision and patient comfort. It follows the same principle as SMILE but offers improved outcomes and a quicker recovery.

4. What is Clear Lens Extraction?
Clear Lens Extraction (Refractive Lens Exchange) involves removing the eye’s natural lens and replacing it with an artificial intraocular lens (IOL). This procedure is similar to cataract surgery and is effective for a wide range of vision problems, including presbyopia.

5. Who is a good candidate for LASIK?
