LASIK (Laser-Assisted In Situ Keratomileusis) reshapes the cornea using an excimer laser to correct refractive errors including myopia, hyperopia, and astigmatism. A thin corneal flap is created, the underlying tissue is reshaped, and the flap is repositioned. The procedure takes approximately 15 minutes per eye with rapid visual recovery.
Full procedure guide →LASIK is an outpatient refractive procedure with a strong safety record when pre-operative screening (corneal topography, pachymetry) excludes keratoconus; the most common longer-term issues are dry eye and minor enhancement requirements. India's refractive surgery centres are concentrated in Mumbai, Delhi, and Bangalore; India regulates physicians through the National Medical Commission (which superseded the Medical Council of India in 2020); NABH operates the leading hospital accreditation programme and consumer commissions hear most clinical-negligence claims. Confirm that pre-operative topography and pachymetry are performed and reviewed by the operating surgeon, not just by technicians; appropriate residual stromal bed thickness is the single most important safety parameter.

India's framework is unusual in giving consumer-protection forums a primary role in clinical negligence claims. Following the Supreme Court's 1995 decision in Indian Medical Association v VP Shantha, medical services fall within the Consumer Protection Act, which means patients can bring claims before consumer commissions at district, state, and national levels — typically with lower court fees, faster timelines, and simpler procedures than ordinary civil courts. The Consumer Protection Act 2019 has expanded jurisdiction and introduced product-liability principles. Disciplinary oversight sits with the National Medical Commission (NMC), which superseded the Medical Council of India in 2020, and with state medical councils. NABH operates the leading national hospital accreditation programme and publishes inspection-pass status. Civil litigation under tort principles remains available but is rarely the first route for foreign patients given the timelines involved. International patients should retain documentation in English where possible; Indian courts and consumer commissions accept English-language filings.

The M-category medical visa requires a letter from the treating Indian hospital confirming the appointment and nature of treatment, along with a standard visa application. It can be obtained for stays of up to sixty days, extendable within India, and includes a companion (attendant) visa for an accompanying family member or carer. Applications are made through the Indian embassy or high commission in the patient's home country.
India uses the Indian Rupee (INR). Major international hospitals in Delhi and Mumbai accept payment by international credit card and can provide cost estimates in US dollars or other currencies. Currency exchange facilities are available at international airports. Bringing a small amount of cash in US dollars or euros provides a useful backup.
English is an official language of India and the working language of the medical profession throughout the country. At JCI and NABH-accredited hospitals catering to international patients, all clinical communication — consultations, discharge summaries, operative notes — is conducted in English as standard. This is one of India's significant practical advantages as a medical tourism destination.
India's the registry-listed private hospitals have twenty-four-hour emergency departments equipped to manage complex medical emergencies. Travel insurance with medical emergency and repatriation coverage is essential, as uninsured emergency care at private hospitals can be expensive. The national emergency number in India is 112, and most major hospitals have dedicated emergency helplines.
The Consumer Protection Act 2019 covers medical negligence, and patients can file complaints with the District, State, or National Consumer Disputes Redressal Commission. This system is more accessible than traditional civil litigation and has a track record of awarding compensation. The National Medical Commission also handles professional misconduct complaints.
Indian hospitals at the international standard routinely prepare comprehensive discharge packages including operative notes, imaging, pathology reports, and post-operative instructions in English. Before discharge, confirm that all documents have been provided and share them with your GP or relevant specialist at home. The international patient department can liaise directly with home-country physicians if needed.
The major medical tourism cities — Delhi, Mumbai, Chennai, and Hyderabad — are navigable and generally safe for international patients when using established transport and accommodation. The hospitals themselves provide comprehensive support including airport pickup, accommodation assistance, and security within the hospital campus. Standard urban precautions apply in the wider city.
Delhi experiences extreme heat in summer (April to June, exceeding 40°C) and a cool winter (November to February). Mumbai is hot and humid year-round with a heavy monsoon season from June to September. For elective procedures requiring outdoor activity during recovery, the October to March window in northern India is generally the most comfortable. Patients recovering in air-conditioned hospital accommodation are less affected by seasonal variation.
NABH — the National Accreditation Board for Hospitals and Healthcare Providers — is India's domestic hospital accreditation body and operates to standards broadly comparable with JCI, though the two are separate schemes. NABH accreditation is widespread across the Indian private hospital sector and provides a meaningful quality signal for domestic and international patients alike.
Yes. The Indian medical visa includes provision for a companion (attendant) visa for one accompanying family member or carer, which allows them to stay for the duration of the patient's treatment. This is a practical and valued feature for patients undergoing complex or lengthy procedures who require support during their stay.
Suitable candidates have stable vision for at least twelve months, adequate corneal thickness, no signs of keratoconus or corneal ectasia, and are not significantly affected by dry eye disease. A comprehensive pre-operative assessment including corneal topography and pachymetry is required to confirm suitability.
The reshaping of the cornea by the laser is permanent, but some patients experience gradual regression — a partial return of their refractive error — over years, particularly those with higher prescriptions. Additionally, LASIK does not prevent the natural development of presbyopia (reading difficulty) with age.
The procedure is performed under topical anaesthetic eye drops and is not painful during treatment. Patients may feel pressure from the suction device used during flap creation. Mild discomfort, light sensitivity, and a watery sensation are typical for the first several hours after surgery.
LASIK creates a hinged corneal flap before laser reshaping; PRK removes the surface epithelium instead, with slower recovery but no flap. SMILE is a newer technique that uses only one laser type and removes a small lenticule of tissue without a flap, potentially reducing dry eye compared with LASIK.
Standard LASIK corrects distance vision and does not address presbyopia, meaning patients over forty may still require reading glasses even after a successful procedure. Monovision LASIK — correcting one eye for distance and the other for near — is an option for some patients but requires a trial with contact lenses first.
Modern laser platforms incorporate real-time eye-tracking systems that automatically adjust the laser delivery to compensate for involuntary eye movement. If movement exceeds the tracker's tolerance, the laser pauses automatically. Patients are asked to focus on a target light but do not need to keep perfectly still.
For most patients, LASIK produces a stable, long-lasting result. The majority of patients maintain their corrected vision for many years, though a small proportion experience regression requiring an enhancement procedure. Age-related changes such as cataracts and presbyopia will occur independently of LASIK over time.
Yes. LASIK is effective for correcting astigmatism as well as myopia and hyperopia, provided the degree of astigmatism is within treatable limits and the corneal thickness is adequate. The laser treatment map accounts for the irregular corneal curvature associated with astigmatism.
