Astigmatism is one of the most common refractive errors in the world, affecting an estimated 1 in 3 people to some degree. Unlike myopia (nearsightedness) or hyperopia (farsightedness) — which cause a uniform blurring of vision — astigmatism causes distorted, blurred vision at all distances because the cornea or lens is shaped more like a rugby ball (oval) than a football (sphere). Light entering the eye focuses at two different points rather than a single point on the retina, resulting in a characteristic blurring that is often worse in one meridian than another.
Mild astigmatism can be managed with glasses or toric soft contact lenses. Moderate to significant astigmatism can be permanently corrected with refractive surgery, eliminating or dramatically reducing the dependence on optical correction. The refractive surgery options for astigmatism — toric LASIK, topography-guided LASIK, SMILE, and PRK — are all routinely performed at India's and UAE's leading refractive surgery centres.
For patients who also have cataract or are already having cataract surgery, toric intraocular lenses (toric IOLs) correct astigmatism at the same time as replacing the cloudy lens, providing spectacle-free vision for distance (and, with premium multifocal toric IOLs, for near as well).
India and the UAE are internationally recognised centres of excellence for refractive surgery, with a high density of ophthalmologists trained in the latest LASIK, SMILE, and PRK platforms. Costs in India are 60–70% below equivalent centres in Europe or North America.
Understanding Astigmatism
The cornea (the clear front surface of the eye) and the crystalline lens are the two refracting elements of the eye. For vision to be sharp, they must have a smooth, spherical curvature that focuses parallel light rays to a precise point on the retina. In astigmatism, the cornea is not spherical but has different curvatures in different meridians — the vertical meridian may be steeper than the horizontal meridian (or vice versa), causing what is called "regular astigmatism" which is correctable with cylindrical spectacle lenses or toric contact lenses.
Irregular astigmatism — in which the corneal surface has an irregular, unpredictable shape — cannot be corrected with standard spectacle lenses and requires rigid gas-permeable contact lenses or surgical intervention. Keratoconus (see the separate section) is the most important cause of irregular astigmatism and is a contraindication to standard LASIK.
Astigmatism is measured in dioptres (D) of cylinder and is described by its axis (the orientation of the steepest corneal meridian). Low astigmatism is less than 1.00 D; moderate astigmatism is 1.00–2.00 D; high astigmatism is greater than 2.00 D. Current laser platforms can correct astigmatism up to 5.00–6.00 D in suitable corneas.
Post-surgical astigmatism can occur after corneal transplantation, cataract surgery, pterygium surgery, or radial keratotomy (an older surgical technique). This type of induced astigmatism can also be addressed with toric IOLs (after cataract or refractive lens exchange), corneal relaxing incisions (limbal relaxing incisions, LRI), or topography-guided laser ablation.
Astigmatism Correction Procedures
The optimal procedure depends on the degree of astigmatism, the corneal thickness, the presence of any corneal irregularity, the patient's age, and the presence of concurrent refractive errors (myopia or hyperopia).
Toric LASIK creates a thin corneal flap with a femtosecond laser and then uses an excimer laser to ablate corneal tissue in a pattern that corrects both the spherical and cylindrical components of the refraction. Wavefront-guided or topography-guided LASIK provides the most precise, customised correction — the ablation pattern is calculated from a detailed map of the patient's corneal shape and wavefront aberrations, rather than just from the spectacle prescription. The procedure is performed under topical anaesthetic eye drops, takes 15 minutes per eye, and provides very rapid visual recovery (20/20 in most patients by the next morning).
SMILE (Small Incision Lenticule Extraction) is a flapless procedure that uses a single femtosecond laser to create a precise disc of corneal tissue (the lenticule) that is removed through a small arc incision. SMILE corrects myopia and astigmatism and has the advantages of a stronger residual corneal structure (no flap), lower dry eye risk, and suitability for contact sport athletes. SMILE for astigmatism correction has outcomes equivalent to LASIK in published clinical trials.
PRK (Photorefractive Keratectomy) or Trans-PRK (transepithelial PRK) corrects astigmatism by ablating the corneal surface directly rather than creating a flap. It is preferred for patients with thin corneas, previous LASIK (for enhancement), or occupations that preclude flap creation. Visual recovery is slower (3–5 days of discomfort) but the long-term result is equivalent to LASIK.
Toric IOLs are implanted during cataract surgery or refractive lens exchange to simultaneously correct the spherical refractive error and the astigmatism. The toric IOL has a cylindrical correction component built into the lens and is aligned with a specific axis in the eye. Premium toric multifocal IOLs can correct astigmatism and provide both distance and near vision without glasses. Toric IOL alignment is the critical technical factor for good outcomes.
Limbal Relaxing Incisions (LRI) / Corneal Relaxing Incisions (CRI) are small arc-shaped incisions placed in the peripheral cornea to flatten the steepest meridian and reduce astigmatism. They are typically used for low to moderate astigmatism as an adjunct to cataract surgery when toric IOL implantation is not used.
Procedure Steps
- Comprehensive pre-operative assessment: manifest refraction, corneal topography (Pentacam, Orbscan), wavefront analysis, corneal thickness (pachymetry), pupil size, tear film assessment
- Suitability confirmed — corneal thickness sufficient, no keratoconus, stable refraction for 12 months
- Topical anaesthetic drops instilled; eyelid speculum placed
- Femtosecond laser creates corneal flap (LASIK) or lenticule (SMILE); no cut for PRK
- Excimer laser ablation guided by wavefront/topography map corrects the cylindrical and spherical error
- Flap repositioned and allowed to adhere (LASIK); or lenticule extracted through arc incision (SMILE)
- Antibiotic and anti-inflammatory drops applied; protective shield placed
- Review at 1 day, 1 week, 1 month, 3 months and 12 months to document outcome

Toric LASIK or SMILE for astigmatism in the USA costs $2,500–$4,500 per eye at premium LASIK centres. In the UK, prices range from £1,800–£3,500 per eye. In India, the same procedure — using identical Alcon WaveLight, Carl Zeiss Meditec VisuMax, or Bausch & Lomb Technolas platforms — costs $700–$1,800 per eye. For a bilateral procedure, the total all-inclusive cost (both eyes, pre-operative assessment, surgery, and postoperative drops) is typically $1,400–$3,600 — compared to $5,000–$9,000 in the USA.
Toric IOL surgery (during cataract extraction) in India costs $1,200–$2,500 per eye depending on the IOL model selected, compared to $3,500–$6,000 in the USA. Premium toric multifocal IOLs (Alcon PanOptix Toric, Johnson & Johnson Synergy Toric) are available at leading Indian centres at $1,800–$3,000 per eye all-inclusive, compared to $5,000–$8,000 in the USA.
Recovery & Follow-up
LASIK recovery is rapid — most patients see well enough to drive the following day. Vision may fluctuate for 2–4 weeks as the corneal surface stabilises, and dry eye is common in the first 1–3 months. SMILE recovery is similar but slightly slower in the first 48 hours. PRK recovery involves 3–5 days of discomfort and blurred vision while the surface epithelium regenerates; vision stabilises over 1–3 months.
The patient must use antibiotic drops for 1 week, anti-inflammatory drops for 2–4 weeks, and artificial tear drops for 1–3 months after surgery. Follow-up examinations at 1 day, 1 week, and 1 month are standard; a 3-month review confirms the outcome is stable. Enhancement (retreatment) is available for small residual refractive errors in most cases after 3–6 months if refraction is stable.
Toric IOL patients recover on the same timeline as standard cataract surgery patients — vision improves progressively over 4–6 weeks as the IOL settles and any corneal incision-related astigmatism resolves. Any rotation of the IOL from its intended axis may require a short repositioning procedure within days if detected early.
Recovery Tips
- Use antibiotic and anti-inflammatory drops strictly as prescribed for the recommended period
- Avoid rubbing your eyes for at least 1 month after LASIK; the corneal flap can be dislodged by pressure or rubbing
- Wear protective sunglasses outdoors — UV exposure can slow surface healing after PRK
- Avoid swimming pools and contact sports for 2–4 weeks
- Use preservative-free artificial tears liberally to manage dry eye in the recovery period
- Attend all follow-up appointments — fine-tuning of outcome and early detection of rare complications requires monitoring
- Carry a copy of your post-operative prescription and surgical report when you travel home
Risks & Complications
Refractive surgery for astigmatism is among the safest procedures in elective medicine. Serious complications are rare at centres with rigorous pre-operative screening. Over-correction or under-correction of astigmatism occurs in a small percentage of cases (2–5%); enhancement procedures are available if the residual error is significant. Regression (gradual partial return of astigmatism) can occur over years, particularly for higher corrections.
Dry eye is the most commonly experienced side effect of LASIK and affects 20–40% of patients in the first 3–6 months; it is usually mild and resolves with artificial tears, though in pre-existing dry eye patients it can be more significant — hence the importance of pre-operative dry eye assessment. SMILE has a lower dry eye risk than LASIK. PRK does not create a flap and has no flap-related risks.
Corneal ectasia — progressive corneal weakening after laser surgery — is the most serious potential complication and occurs in approximately 0.04–0.06% of LASIK eyes, almost always in cases where pre-operative screening failed to detect pre-existing keratoconus or thin corneas. This is why comprehensive pre-operative corneal topography and pachymetry are non-negotiable. At GAF Healthcare's partner centres, no patient proceeds to LASIK without a full Pentacam tomography report reviewed by the refractive surgeon.
Why GAF Healthcare
GAF Healthcare partners with refractive surgery centres that use only the latest-generation laser platforms (Alcon WaveLight EX500, Zeiss VisuMax, Schwind Amaris) with wavefront-guided or topography-guided ablation profiles.

We provide a detailed post-operative summary in English (and Arabic or Russian on request) to share with your home eye care provider.
Frequently Asked Questions
Can LASIK fully correct astigmatism?
Yes, in the large majority of patients. Modern wavefront-guided and topography-guided LASIK platforms can correct astigmatism up to 5.00–6.00 dioptres with excellent precision. In published series, over 90% of patients achieve within 0.50 D of their target refraction after toric LASIK. For very high astigmatism (greater than 4.00 D) or irregular astigmatism, the achievable outcome may be less predictable and a phakic IOL or toric IOL may be a better option.
What is the difference between LASIK and SMILE for astigmatism?
Both procedures provide equivalent visual outcomes for myopic astigmatism. LASIK creates a corneal flap and uses two laser systems; SMILE is flapless and uses only the femtosecond laser. SMILE's advantages for astigmatism patients include: lower dry eye risk, stronger corneal structure, and suitability for patients who want to continue contact sports. LASIK's advantages are faster visual recovery (20/20 by the next morning versus 2–5 days for SMILE) and a slightly broader treatment range. SMILE is not yet available at all Indian centres.
I have both myopia and astigmatism — can both be corrected at the same time?
Absolutely. All modern refractive surgery platforms (LASIK, SMILE, PRK) can simultaneously correct myopia (nearsightedness) and astigmatism in a single treatment. The excimer laser ablation profile is calculated to correct both components at once. Similarly, toric IOLs correct the spherical refractive error and the cylindrical astigmatism simultaneously. This combined correction is the standard of care.
I was rejected for LASIK elsewhere — can I still have my astigmatism corrected?
Rejection from LASIK does not mean all refractive surgery options are closed. The most common reasons for LASIK rejection are thin corneas, early keratoconus, severe dry eye, or prescription outside the treatment range. For thin corneas or mild keratoconus, PRK or SMILE (which remove less corneal tissue) may be appropriate; for keratoconus, cross-linking stabilisation followed by toric IOL or scleral contact lenses are options; for very high astigmatism, a phakic ICL with toric correction may achieve results not possible with laser surgery. A detailed assessment at GAF Healthcare's partner centres will determine the best option for your specific anatomy.
