Before You Travel
Prepare for your Refractive Lens Exchange (RLE) journey
Medical Records & Eye History
Gather what you have at home — your Thai hospital handles the detailed eye testing
- Gather your current glasses or contact lens prescription from your optometrist
- Collect any recent eye exam records — especially retinal scan or OCT results if you have high myopia
- Note your contact lens type (soft, or hard/rigid) — this affects how early you need to stop wearing them
- Your full pre-surgical assessment — corneal mapping, retinal scan, and lens measurements — will be done at your hospital in Thailand
- If you have diabetes, glaucoma, or other conditions affecting your eyes, bring recent health records
Contact Lenses & Health Prep
Stop lenses on time and review medications with your doctor at home
- Stop soft contact lenses at least 1-2 weeks before your first appointment in Thailand (your surgeon will confirm the exact date)
- Stop hard or rigid contact lenses at least 3-4 weeks before your appointment — wear glasses during this time
- Review any eye drops, blood thinners, or supplements with your doctor at home before traveling
- If you have dry eyes, mention this to your surgeon — it can affect which lens type is recommended for you
Consultation with Your Thai Surgeon
Connect with your surgeon before you travel to plan your lens choice and confirm your schedule
- Share your glasses prescription and any existing eye exam records with your surgeon ahead of arrival
- Discuss your daily visual needs — near work, screen time, driving at night — so your surgeon can recommend the best lens option
- Plan for 10-14 days in Thailand if having both eyes done, with the second eye typically 1-2 weeks after the first
- Ask your surgical team how to coordinate follow-up care with a local eye specialist after you return home
Travel & Logistics
Practical planning for your trip and recovery stay
- Book accommodation close to your hospital — both Bumrungrad and Bangkok Hospital have nearby hotel options
- Arrange for a companion on surgery days, as you won't be able to drive after the procedure
- Bring dark sunglasses and avoid eye makeup from surgery day through early recovery
- Consider travel insurance that covers elective medical procedures abroad — see our insurance guide for options suited to vision surgery

Frequently Asked Questions
At what age should I consider RLE vs. LASIK?
Generally, LASIK is preferred for patients under 40-45. RLE becomes more attractive after 45-50 when presbyopia develops and the natural lens is aging. For high hyperopia or thin corneas, RLE may be considered earlier.
Will I still need reading glasses after RLE?
With monofocal IOLs, yes. With premium multifocal, EDOF, or trifocal IOLs, 80-95% of patients achieve good spectacle independence for most activities. About 4 out of 5 people don't need glasses at all after surgery. Some may still prefer readers for fine print in dim lighting.
What are halos and glare?
Multifocal IOLs split light into multiple focal points, which can cause rings around lights (halos) and glare, especially at night. Most patients adapt over 3-6 months. EDOF lenses have less halos (85% report little to none) compared to trifocals (69% report little to none).
Is RLE reversible?
No. Unlike ICL, the natural lens is permanently removed. However, if needed, the IOL can be exchanged for a different type, though this is more complex than the original surgery. Light Adjustable Lens (LAL) offers post-op customization to reduce need for exchange.
Can I have RLE if I've had LASIK?
Yes. Prior LASIK complicates IOL power calculations, but modern formulas (ASCRS post-refractive IOL calculator) handle this well. Provide your pre-LASIK records if available.
How is RLE different from cataract surgery?
The procedure is identical. The difference is RLE is elective (clear lens) while cataract surgery is medically indicated (cloudy lens). Insurance typically covers cataract surgery but not RLE.
What if I'm unhappy with my IOL?
IOL exchange is possible but more complex than the original surgery. Careful IOL selection is critical. Some doctors offer Light Adjustable Lens (LAL) which can be fine-tuned after surgery.
Why might RLE be better than phakic IOL for me?
RLE is preferred if you're over 45-50, have presbyopia, high hyperopia, shallow anterior chamber, or early lens changes. Phakic IOL is better for younger patients (21-45) who want to preserve accommodation.
Important: This information is for educational purposes only and does not constitute medical advice. RLE candidacy depends on individual eye characteristics, age, refractive error, lens condition, and overall eye health. You must consult with a qualified ophthalmologist who can examine your eyes and review your complete medical history before making any decisions about refractive lens surgery. Results vary by individual, and not everyone is a suitable candidate for RLE. Prices shown are estimates and actual costs vary based on IOL selection, surgeon, and facility.
Refractive Lens Exchange (RLE), also known as Clear Lens Extraction or Lens Replacement Surgery, is a vision correction procedure that removes the eye’s natural clear lens and replaces it with an artificial intraocular lens (IOL). The procedure is essentially identical to modern cataract surgery but is performed electively before a cataract develops, purely for vision correction.
RLE is particularly valuable for patients over 45-50 who want freedom from glasses and are not ideal candidates for laser vision correction (LASIK, SMILE, PRK). By replacing the aging natural lens with a premium multifocal or extended depth of focus IOL, RLE can provide clear vision at all distances while eliminating the future development of cataracts. According to clinical studies, 90%+ achieve 20/20 vision or better, with 95% patient satisfaction reported by Cleveland Clinic.
According to the 2022-2023 EUROQUO Annual Report, RLE represents approximately 80% of reported refractive surgery cases worldwide, making it the most commonly performed refractive surgery globally.
IOL Options
Your choice of intraocular lens determines your visual outcome:
| IOL Type | Distance Vision | Near Vision | Spectacle Independence | Halos/Glare |
|---|---|---|---|---|
| Monofocal | Excellent | Glasses needed | 36% | Minimal |
| EDOF | Excellent | Sometimes glasses | 74% | Mild (15% report) |
| Trifocal | Excellent | Very good | 92% | Moderate |
Premium IOL brands available in Thailand include:
- Alcon PanOptix (trifocal) — highest spectacle independence
- Alcon Vivity (EDOF) — lowest halos and glare
- J&J Synergy (hybrid EDOF/multifocal) — extended range
- RxSight LAL (Light Adjustable Lens) — post-operative customization
- Zeiss AT LISA tri (trifocal) — European standard
A mix-and-match approach—combining different IOL types in each eye (e.g., trifocal + EDOF)—can optimize results by combining advantages of each lens.
RLE vs. Other Refractive Procedures
| Factor | RLE | LASIK | ICL |
|---|---|---|---|
| Best Age | 45+ | 18-55 | 21-45 |
| Corrects Presbyopia | Yes | No | No |
| Maximum Correction | Unlimited | ±12D | ±20D |
| Eliminates Future Cataracts | Yes | No | No |
| Preserves Natural Lens | No | Yes | Yes |
| Reversible | No | No | Yes |
| Recovery Time | 1-3 months | 1-3 days | 1-2 days |
RLE is preferred over phakic IOL when you have presbyopia (age 45+), high hyperopia, a shallow anterior chamber unsuitable for phakic lens, or early lens changes.
Important Risk Considerations
Retinal Detachment Risk:
- Overall incidence: approximately 1-2%
- Risk increases with high myopia (>-10D) and longer axial length (>27mm)
- Age factor: Under 50 years: ~5% vs. over 70 years: ~0.6%
- Thorough preoperative retinal examination is essential
- Younger high myopes may be better candidates for ICL
Your surgeon will discuss your individual risk profile based on your specific eye characteristics.
International Patient Considerations
As a medical tourism patient, coordinating follow-up care is essential:
- Pre-travel planning: Identify a local ophthalmologist who can provide post-operative care or emergency treatment after you return home
- Medical records: Request complete surgical records including IOL card (lens specifications), imaging, and post-operative instructions
- Stay duration: Plan for 10-14 days in Thailand to allow for both eye surgeries and initial recovery
- Travel timing: Flying is generally safe 24-48 hours after each eye; no gas bubble restrictions apply (unlike retinal surgery)
- Follow-up protocol: Initial checks occur before you leave Thailand; subsequent follow-ups at 1, 3, and 6 months can often be coordinated with your local ophthalmologist
- Emergency contacts: Obtain 24/7 contact information for urgent concerns
Some complications require prompt attention and may need care from a local provider after you return home. Discuss international care coordination with your surgical team before your procedure.
