Refractive Surgery & Vision Correction at Anand Eye Centre
Refractive surgery includes laser and lens-based procedures that may reduce dependence on spectacles or contact lenses. At Anand Eye Centre, evaluation focuses on eye health, corneal suitability, prescription stability and realistic expectations before advising any procedure.
What is refractive surgery?
Refractive surgery is a group of procedures designed to correct spectacle power and reduce dependence on glasses or contact lenses. Depending on the eye condition, this may involve reshaping the cornea using a laser or using a lens-based solution.
It may be considered for myopia, hyperopia, astigmatism or age-related near vision concerns in selected patients. The right procedure depends on age, prescription, corneal thickness, corneal shape, dry eye status, retina health, lifestyle and expectations.
Laser vision correction
Procedures such as LASIK or PRK reshape the cornea to reduce spectacle power in suitable candidates.
Implantable lens correction
ICL may be considered where lens-based correction is more suitable than corneal laser correction.
Refractive lens exchange
RLE is a lens replacement procedure considered in selected patients, especially where age or lens status matters.
Who may be considered for refractive surgery?
A person may be evaluated for refractive surgery if they want to reduce dependence on glasses or contact lenses and have a stable prescription. However, final suitability depends on detailed examination and diagnostic testing.
Some patients are better suited for LASIK or PRK, while others may need lens-based procedures such as ICL or refractive lens exchange. In some cases, surgery may not be advised.
Usually considered after 18 years of age with stable spectacle power.
Corneal thickness, shape and surface health must be suitable.
Dry eye, infection, inflammation, keratoconus, glaucoma or retina issues must be ruled out.
The goal is reduced dependence on glasses, not a guaranteed perfect outcome for every patient.
Types of refractive surgery options
Different refractive procedures solve different problems. The doctor recommends the option only after assessing prescription, corneal measurements, lens status, eye pressure, retina and lifestyle needs.
LASIK
LASIK is a laser vision correction procedure commonly considered for suitable patients with myopia, hyperopia or astigmatism. It requires proper corneal thickness and shape, stable power and absence of contraindications.
PRK
PRK is a surface-based laser correction option. It may be considered in selected cases where LASIK is not the preferred approach. Recovery may differ from LASIK and is explained during consultation.
ICL / Implantable Collamer Lens
ICL is a lens-based option for selected patients, especially where spectacle power is high or corneal laser correction may not be suitable. Eye size, chamber depth and retina health are important.
Refractive Lens Exchange
Refractive lens exchange is similar in concept to cataract surgery, where the natural lens is replaced with an intraocular lens. It may be considered in selected older patients or those not suitable for laser correction.
How refractive surgery evaluation is done
A refractive surgery consultation is more detailed than a routine power check. It includes measurements that help identify whether the eye is safe for surgery and which procedure may be appropriate.
Vision and prescription assessment
Current spectacle power, stability of prescription, age, occupation and visual needs are reviewed.
Cornea and dry eye assessment
Corneal thickness, shape, surface health and dry eye status are assessed because these strongly influence suitability.
Eye pressure and dilated retina check
Eye pressure, retina health and optic nerve condition may be evaluated before planning refractive surgery.
Procedure matching
The doctor explains whether LASIK, PRK, ICL, RLE or no surgery is appropriate based on diagnostic findings.

What can refractive surgery help with?
Refractive surgery may reduce dependence on glasses or contact lenses for distance vision, depending on the procedure and patient profile. It can be helpful for people who find spectacles inconvenient for work, sports, travel or daily life.
However, it does not prevent all future eye conditions, and some patients may still need glasses for certain tasks, especially reading after presbyopia age or in specific lighting conditions.
Many suitable patients experience reduced need for glasses or contact lenses.
Helpful for selected patients involved in travel, sports or active routines.
Laser and lens-based options can be considered depending on the eye.
Post-procedure care and reviews are required for healing and visual recovery.
Refractive surgery may be considered for:
- Myopia or near-sightedness
- Hyperopia or far-sightedness
- Astigmatism
- Selected cases of presbyopia-related needs
- Patients seeking reduced dependence on spectacles
- Patients unable to tolerate contact lenses
- Patients not suitable for one option but suitable for another
What is refractive lens exchange?
Refractive lens exchange, also called RLE, is a lens replacement procedure. It is conceptually similar to cataract surgery, except it may be performed for refractive correction in selected patients even when a visually significant cataract is not the main reason.
During RLE, the natural lens is replaced with an intraocular lens. It may be discussed in selected patients who are not ideal candidates for corneal laser correction or who have age-related vision needs where lens-based planning is more suitable.
Lens-based approach
The natural lens is replaced with an intraocular lens selected according to eye measurements and visual needs.
Useful in selected cases
May be considered when LASIK or PRK is not suitable, especially in older patients or high refractive errors.
Requires detailed counselling
Lens choice, reading vision, glare, halos, retina status and long-term expectations should be discussed.
Refractive surgery connects with complete eye care
Vision correction planning often needs support from diagnostics, cornea evaluation, dry eye management, retina assessment and cataract/lens planning. These pages help patients understand the complete pathway.
Want to know whether LASIK, PRK, ICL or lens-based correction is suitable for you?
A refractive surgery eligibility check helps identify the safest and most suitable approach for your eyes. The final recommendation depends on examination, diagnostics and counselling.
Helpful details to share
- Current spectacle or contact lens power
- Whether power has changed recently
- Age and occupation
- Dry eye, allergy or eye rubbing history
- Previous eye surgery or injury
- History of high myopia, glaucoma or retina problems
Frequently asked questions on refractive surgery
These answers are general and do not replace personal medical advice. Final suitability for any refractive procedure depends on detailed eye examination and diagnostic testing.
Is refractive surgery the same as LASIK?
No. LASIK is one type of refractive surgery. Refractive surgery also includes PRK, ICL and refractive lens exchange in selected patients.
Who is a good candidate for refractive surgery?
A suitable candidate usually has stable spectacle power, appropriate age, healthy cornea, acceptable eye pressure, no active eye disease and realistic expectations. Final eligibility is decided after testing.
Is refractive surgery painful?
Most procedures are performed with anaesthetic eye drops or appropriate anaesthesia. Patients may feel pressure, watering or mild discomfort depending on the procedure and recovery phase.
Can refractive surgery completely remove glasses?
Many suitable patients experience reduced dependence on glasses, but complete freedom from glasses cannot be guaranteed for every patient. Reading glasses may still be needed with age-related near vision changes.
What tests are needed before LASIK or PRK?
Testing may include prescription assessment, corneal thickness, corneal topography, dry eye evaluation, pupil assessment, eye pressure check and retina examination.
What is ICL?
ICL is an implantable lens placed inside the eye in selected patients. It may be considered when laser corneal correction is not suitable or when refractive power is high.
What is refractive lens exchange?
Refractive lens exchange is a lens replacement procedure similar in concept to cataract surgery. It may be considered in selected patients where lens-based correction is more appropriate than laser correction.
Can dry eye affect refractive surgery suitability?
Yes. Dry eye can affect comfort, healing and visual quality after surgery. It should be evaluated and treated before considering refractive surgery.
