LASER & ADVANCED PROCEDURES
Laser vision correction FAQs
Considering laser eye surgery in Mumbai? Truevision Eye Hospital explains common vision-correction options, who may be suitable, recovery and risks. Dr Jinish Upadhyay can discuss your individual assessment and treatment options. Suitability and results vary.
OPTIONS
Understanding your options
What is laser vision correction?
It reshapes the cornea so light focuses more clearly on the retina. It can reduce dependence on glasses or contact lenses for myopia (short-sightedness), hyperopia (long-sightedness) and astigmatism. It does not prevent age-related reading-glass needs or future eye disease.
Which procedures are commonly considered?
Corneal laser options include LASIK, SMILE and surface treatments such as PRK, LASEK and TransPRK. Implantable collamer lenses (ICL) sit inside the eye while the natural lens remains. Refractive lens exchange (RLE) removes the natural lens and replaces it with an artificial lens. Glasses and contact lenses remain safe, effective alternatives.
How do LASIK, SMILE and PRK differ?
LASIK creates a thin corneal flap, reshapes tissue beneath it and replaces the flap. SMILE removes a small lens-shaped piece of corneal tissue through a small incision, without a flap; availability and treatable prescriptions depend on the laser platform and local approval. PRK and related surface ablation remove the surface layer and reshape the cornea without a flap. LASEK preserves and replaces a thin surface layer; TransPRK uses a laser for the surface step. Suitability varies.
How do ICL and RLE differ from laser procedures?
ICL is an implant placed inside the eye without removing the natural lens; it may be considered for some people with higher prescriptions or corneas unsuitable for laser, after detailed measurements. RLE replaces the natural lens, much like cataract surgery, and is sometimes considered when age, prescription or lens status makes corneal laser less suitable. Both are intraocular operations with different risks and follow-up needs.
Is one procedure best for everyone?
No. The right option depends on prescription and its stability, corneal shape and thickness, tear-film health, pupil and eye measurements, age, occupation, sports, general health and visual priorities. A surgeon may recommend no surgery.
CANDIDACY
Candidacy and decision-making
Who may be considered?
Adults with a stable prescription and healthy eyes may be assessed. Minimum age and prescription limits differ by procedure, device and local regulation. The surgeon must confirm that treatment is within the approved range and that expected benefits justify the risks.
Who may need to avoid or delay surgery?
A changing prescription, pregnancy or breastfeeding, significant dry eye, keratoconus or suspicious corneal maps, thin or scarred corneas, uncontrolled diabetes, active eye disease, cataract, certain autoimmune conditions or medicines, and unrealistic expectations can affect suitability or timing. This list is not complete.
What tests are done before deciding?
Assessment usually includes a detailed prescription and eye-health examination, corneal mapping and thickness, tear-film evaluation, pupil and eye-pressure checks, and measurements tailored to the procedure. Contact lens use can alter corneal measurements; follow the clinic’s instructions on when to stop wearing lenses before testing.
Can surgery guarantee 20/20 vision or freedom from glasses?
No. Many people reduce their dependence on glasses, but no result is guaranteed. Residual prescription, enhancement, glasses for some tasks, or future reading glasses may still be needed. Results can change with healing and age.
What should I ask at consultation?
Ask which options suit your eyes and why; what the surgeon’s own outcomes and complication rates are; what night-vision or dry-eye symptoms to expect; whether glasses may still be needed; what follow-up and enhancement costs apply; and how the procedure may affect future eye care or work requirements.
RECOVERY AND RISKS
Recovery and risks
What is recovery like?
Vision often clears quickly after LASIK, though it can fluctuate. SMILE recovery is also generally rapid but varies. PRK/surface ablation usually causes several days of discomfort and slower visual recovery while the surface heals; vision may fluctuate for weeks. ICL and RLE recovery varies after intraocular surgery. Follow the individual surgeon’s instructions and attend all reviews.
What are common side effects?
Temporary dryness, irritation, light sensitivity, fluctuating or hazy vision, glare, halos or starbursts can occur after corneal procedures. PRK may involve more early discomfort and temporary haze. Symptoms usually improve, but some can persist. Night driving may be difficult for some people.
What serious complications are possible?
Uncommon complications include infection, inflammation, scarring or corneal haze, under- or over-correction, loss of best-corrected vision, corneal weakening (ectasia), and need for further treatment. LASIK has flap-related risks. ICL can involve raised eye pressure, cataract, endothelial cell loss, lens sizing or positioning problems, and need for another operation. RLE has risks of cataract-type surgery, including retinal detachment, infection, inflammation, and unwanted optical effects. Individual risk depends on the eye and procedure.
Can my eyesight change later?
Yes. Natural ageing can cause presbyopia (difficulty focusing up close) and cataract. The eye’s prescription can also change. Laser correction does not stop these changes. Keep your pre- and post-operative records and continue routine eye examinations.
CONSULTATION
Consultation at Truevision Eye Hospital
How do I prepare for a consultation?
Bring your current and previous prescriptions, medication list, relevant medical and eye history, and any work or sports requirements. Be ready to discuss night driving, screen use, contact sports and whether you are comfortable using glasses for some activities.
How can I discuss laser vision correction with Dr Jinish Upadhyay?
Book a comprehensive refractive assessment at Truevision Eye Hospital in Mumbai. Dr Jinish Upadhyay can discuss your prescription, eye measurements, lifestyle and treatment options, including whether surgery is suitable. Use the visit to compare alternatives and take time before deciding. The examination may show that glasses, contact lenses or no treatment are the best choice.
