Lasik Surgery
Refractive Surgery: Procedures for Vision Correction
Refractive surgery includes surgical procedures used to correct certain refractive errors of the eye. The choice of procedure depends on an individual’s prescription, corneal characteristics, overall eye health and clinical suitability.
LASIK Surgery Benefits
Understanding Refractive Surgery
People may explore refractive surgery for different reasons, including their visual requirements, occupational needs or preference for reduced dependence on spectacles or contact lenses. Suitability varies between individuals, and surgery may not eliminate the need for spectacles in every situation
What Is Refractive Surgery?
- Refractive surgery refers to procedures that aim to reduce dependence on spectacles or contact lenses by changing how light is focused on the retina.
- Depending on the procedure, this may involve reshaping the cornea or implanting or replacing a lens within the eye.
- Refractive errors include myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. Presbyopia, an age-related change in near vision, may also be addressed through selected treatment approaches.
- Not every person is suitable for every procedure. A comprehensive ophthalmic examination is required before treatment can be considered.
Refractive Surgery Procedures
LASIK
Laser-Assisted In Situ Keratomileusis (LASIK) is a procedure in which a thin flap is created in the cornea, and an excimer laser reshapes the underlying corneal tissue to correct refractive error.
SMILE
Small Incision Lenticule Extraction (SMILE) is a laser procedure in which a small piece of corneal tissue is removed through a small incision to correct selected refractive errors.
Topography-Guided LASIK (Contoura Vision)
This approach uses corneal topography to guide laser treatment planning. Its suitability depends on corneal measurements, refractive error and other clinical findings.
PRK
Photorefractive Keratectomy (PRK) is a surface-based laser procedure in which the corneal surface layer is removed before laser reshaping. Recovery and healing differ from those associated with LASIK.
Implantable Collamer Lens (ICL)
An implantable collamer lens is placed inside the eye while the natural crystalline lens is retained. It may be considered for selected patients after assessment of refractive error, anterior eye anatomy and other relevant factors.
Refractive Lens Exchange (RLE)
Refractive lens exchange involves replacing the eye’s natural lens with an artificial intraocular lens. It may be considered in selected patients following an assessment of their visual requirements, lens status and overall eye health.
Each procedure has specific indications, limitations and potential risks. The treating ophthalmologist should explain the relevant options before a decision is made.
LASIK vs Glasses vs Contact LensesWhat's Actually Different?
| Comparison | Refractive Surgery | Glasses | Contact Lenses |
|---|---|---|---|
| Corrects Vision By | Procedures that reshape the cornea or involve an intraocular lens. | External optical correction. | External optical correction. |
| Daily Dependency | May reduce dependence on corrective eyewear; spectacles may still be needed. | Worn as required for vision correction. | Worn as prescribed, with appropriate care. |
| Best Suited For | Individuals assessed as clinically suitable for a particular procedure. | Individuals requiring optical vision correction. | Individuals suitable for contact lens wear. |
| Ongoing Cost | Procedure, assessment and follow-up costs. | Frames and prescription updates, as required. | Lenses, solutions and replacements, as required. |
| Suitability Decided By | Comprehensive ophthalmic evaluation. | Appropriate prescription. | Appropriate fitting and eye assessment, where indicated. |
LASIK Options
Who May Need to Wait for LASIK or Explore Other Options?
Certain clinical findings may require further evaluation, treatment before surgery, postponement or consideration of an alternative procedure. These may include:
Those with an unstable or still-changing prescription
Those with thin corneas or certain corneal conditions, evaluated on a case-by-case basis
Pregnant or breastfeeding women, when hormonal changes may affect refractive measurements.
Those with active or inadequately managed dry eye disease.
Those with certain autoimmune or connective tissue conditions.
Those with refractive errors outside the suitable range for the proposed procedure.
Those with signs of keratoconus or other corneal irregularities on mapping.
Those with uncontrolled diabetes or other conditions that may affect healing and eye health.
Which Refractive Procedure Is Right for You? Understanding the Technology
“`html
| Types of Refractive Surgery | What It Means | Best For |
|---|---|---|
| LASIK (Laser-Assisted In Situ Keratomileusis) | Involves creating a thin corneal flap and reshaping the underlying corneal tissue with an excimer laser. | Patients assessed as clinically suitable for LASIK following a comprehensive evaluation. |
| Contoura Vision (Topography-Guided LASIK) | Uses corneal topography to guide treatment planning based on the patient’s corneal measurements and clinical findings. | Selected patients for whom topography-guided treatment is considered appropriate following evaluation. |
| SMILE (Small Incision Lenticule Extraction) | A laser procedure in which a small lenticule of corneal tissue is removed through a small incision. | Patients who meet the clinical criteria for the procedure. |
| PRK (Photorefractive Keratectomy) | A surface-based laser procedure in which the outer corneal layer (epithelium) is removed before reshaping the cornea. No corneal flap is created. | Selected patients based on corneal characteristics, refractive error and other clinical findings. |
| ICL (Implantable Collamer Lens) | A lens is implanted inside the eye without removing the natural crystalline lens. | Selected patients assessed for the procedure based on refractive error and ocular anatomy. |
| Refractive Lens Exchange (RLE) | The eye’s natural lens is replaced with an artificial intraocular lens. | Selected patients following assessment of refractive error, lens status and overall eye health. |

A Note on “Which One’s Best For Me”: Each procedure has potential benefits, limitations, risks and complications. The treating ophthalmologist should explain the relevant considerations, expected recovery, available alternatives and individual suitability before a treatment decision is made.
A Step-by-Step Overview of Refractive Surgery
Step 1
Comprehensive eye evaluation
Corneal mapping, corneal thickness measurement, refractive testing, ocular surface evaluation and other examinations may be performed according to the patient's clinical requirements.
Step 2
Discussion of treatment options
Following the evaluation, the ophthalmologist discusses whether surgery is appropriate, the procedures that may be considered, their potential risks and limitations, and available alternatives.
Step 3
Recovery and follow-through
Postoperative instructions and follow-up appointments are provided according to the procedure and the patient's clinical requirements to assess healing and visual changes.
Tips for Post-Surgery Care
Postoperative instructions vary according to the procedure and the patient’s clinical condition. The following general guidance should be followed alongside the instructions provided by the treating ophthalmologist:
- Avoid rubbing or pressing on the eyes during the recovery period specified by the treating ophthalmologist.
- Use prescribed eye drops exactly as directed.
- Follow advice concerning dust, wind, water exposure and other activities during the recovery period.
- The time needed to resume desk work and normal activities varies by procedure and individual healing. Follow the instructions provided by the treating ophthalmologist.
- Use sunglasses or other protective measures when recommended by the treating ophthalmologist.
- Attend scheduled follow-up appointments to assess healing and visual changes.
- Contact an ophthalmologist promptly if you experience severe pain, a sudden decrease in vision, increasing redness, unusual discharge, flashes or new floaters.
