Surgical precision for prescriptions that sit beyond every other refractive option.
Phakic IOLs treat the prescriptions that nothing else can reach — extreme myopia, significant hyperopia, and complex astigmatism beyond the range of every laser procedure. A precision-engineered lens is placed inside the eye alongside your natural lens, correcting the refractive error without altering the cornea. Thailand's anterior segment specialists have deep experience with both iris-fixated and posterior chamber designs.
Free, no-obligation — you pay the hospital directly with no markup.
A phakic IOL is implanted while the natural crystalline lens is preserved. Unlike laser procedures that reshape the cornea, phakic IOLs add optical power inside the eye. They can treat myopia exceeding -20.00 dioptres, significant hyperopia, and complex astigmatism that no corneal procedure can safely address.
Two principal design families exist. Posterior chamber models sit behind the iris in the ciliary sulcus. Anterior chamber iris-fixated models attach to the iris itself. Each has distinct surgical characteristics and suitability criteria. Thailand's eye hospitals offer both, and the choice is driven by your anatomy and refractive error rather than commercial preference.
Phakic IOL implantation requires subspecialist expertise in anterior segment surgery. Thailand's major eye centres have dedicated anterior segment departments with the biometric imaging and surgical experience to handle complex cases confidently.

Your Quote Will Include
Prices are approximate and vary by technique, surgeon, and hospital. Your personalised quote will include a full cost breakdown.
Phakic IOL surgery in Thailand typically costs between $3,800 and $6,800 for both eyes. The lens itself accounts for a significant portion of the total. Anterior chamber iris-fixated models and posterior chamber ICLs are priced comparably. The difference in total cost between the two is primarily driven by surgeon and facility fees.
The total includes the phakic IOL lenses, comprehensive biometric assessment, surgeon fees, anaesthesia, facility charges, post-operative medications, and follow-up appointments during your stay. Specific lens models and powers may affect the final quote. Toric variants for astigmatism correction may carry a small additional charge.
The main variables are the lens type and whether astigmatism correction is included. Toric models cost more. The choice between anterior and posterior chamber placement may also affect pricing slightly. Surgeon experience and hospital accreditation level influence facility fees but not the lens cost itself.
Pricing varies by the complexity and scope of the procedure. Typical ranges at our partner hospitals in Thailand:
Exact pricing is confirmed after your consultation and treatment plan are finalised.
Phakic IOL surgery in Thailand costs 40–60% less than in the US ($9,500–$15,200), Australia (A$8,700–A$14,400), and UK (£7,600–£13,300). Lens costs are similar worldwide. The savings reflect lower Thai surgical and facility fees at JCI-accredited centres that maintain international safety standards.
The two families of phakic IOL differ in where they sit inside the eye and what they are best suited to correct. Your anatomy — specifically anterior chamber depth, endothelial cell count, and iris configuration — determines which type is appropriate.
Positioned in front of the iris and secured by enclavation — clipping onto the mid-peripheral iris tissue. Has a long clinical track record exceeding 25 years and can correct both very high myopia and significant hyperopia, making it more versatile than posterior chamber models for hyperopic correction.
Sits behind the iris in the ciliary sulcus, between the iris and natural lens. The EVO+ ICL uses biocompatible Collamer material with a central aqueous port. Cosmetically invisible and optically excellent for high myopia up to -18.00 dioptres. The most commonly implanted phakic IOL type globally.
Surgical technique differs between anterior and posterior chamber models, but both demand precise pre-operative biometry and careful intraocular handling. The measurement phase is as important as the surgery itself.
Anterior segment OCT, Scheimpflug imaging, ultrasound biomicroscopy, and specular microscopy map your anterior chamber dimensions, endothelial cell density, and iris anatomy. These measurements determine the lens type, size, and power. Cutting corners here is the primary cause of post-operative complications.
A wider incision (approximately 5–6mm) is required for rigid iris-fixated lenses. The lens is positioned in the anterior chamber and the mid-peripheral iris is enclavated under direct visualisation. Sutures may be placed in the incision depending on its size.
Vision improves significantly within hours. Mild blurring from corneal oedema and pupil dilation may persist briefly. Anti-inflammatory and antibiotic drops begin. A protective shield is worn for sleeping.
Vision sharpens as corneal clarity returns and the pupil normalises. Implant position, pressure, and endothelial response are checked at follow-up. Light daily activities can resume. Avoid heavy lifting and straining.
The incision heals fully and the eye settles around the implant. Anti-inflammatory drops are tapered. Moderate exercise and driving can resume once the surgeon confirms adequate acuity.
Vault or anterior chamber clearance, endothelial cell count, and pressure are measured to confirm long-term stability. All activities including swimming can resume. The refraction is verified and the implant assessed in its permanent position.
Most patients can fly home 5–7 days after surgery, once the implant position and pressure have been confirmed stable at follow-up. Flying does not affect the lens. Both eyes are typically treated on separate days, so plan your departure based on follow-up after the second eye.
Desk work can resume within 3–5 days. Light exercise after a week. Swimming and strenuous activities should wait 3–4 weeks to allow the incision to seal completely — particularly important for iris-fixated lenses where the incision is larger. No contact sports until cleared by your surgeon.
Visual improvement is dramatic within the first 24 hours. The refraction stabilises within the first week for most patients. A comprehensive assessment at 1–3 months confirms the final result including endothelial cell count and long-term implant position. Ongoing annual monitoring is recommended.
Phakic IOL implantation is an intraocular procedure with well-documented risks that differ from corneal laser surgery. Understanding these is particularly important because the lens remains inside the eye long-term.
Long-term safety depends on proper lens selection, accurate sizing, and regular follow-up monitoring of endothelial cell density and intraocular pressure. Our partner surgeons decline to proceed when safety margins for chamber depth or cell density are not met. That selective approach protects long-term outcomes.
Yes. Thailand's anterior segment surgery centres hold JCI accreditation and maintain the full suite of biometric imaging required for safe phakic IOL implantation. Our partner surgeons are fellowship-trained in anterior segment surgery with specific phakic IOL experience. They follow international safety protocols including minimum endothelial cell count thresholds and chamber depth requirements.
Demand comprehensive biometric imaging — anterior segment OCT, ultrasound biomicroscopy, Scheimpflug, and specular microscopy. A centre that skips any of these modalities is taking shortcuts. Endothelial cell count must be above the safe threshold before surgery, and should be monitored annually afterward. Choose a surgeon who will decline to operate if the safety margins are not met.
Annual follow-up with your local ophthalmologist is essential after phakic IOL implantation. Endothelial cell density should be measured yearly to track any progressive loss. Intraocular pressure and implant position should be assessed at each visit. If significant cell loss is detected, the lens may need to be removed before endothelial decompensation occurs — catching this early is the purpose of regular monitoring.
Phakic IOL implantation is a subspecialist procedure requiring specific training and equipment that not every eye centre offers.
Our partner hospitals have dedicated anterior segment departments with the complete suite of biometric imaging, including anterior segment OCT, ultrasound biomicroscopy, Scheimpflug cameras, and specular microscopy. They stock both iris-fixated and posterior chamber lens designs, allowing the surgeon to recommend based on anatomy rather than inventory.
Our partner surgeons hold fellowships in anterior segment and refractive surgery. They have experience with both iris-fixated and posterior chamber phakic IOLs and can recommend the most appropriate design for your specific anatomy and refractive error. That breadth of experience matters because a surgeon who only implants one type will recommend that type regardless.
Check for specific anterior segment fellowship training. Ask about their experience with both iris-fixated and posterior chamber designs. Enquire about their endothelial cell monitoring protocol and how they decide when to recommend lens removal. A surgeon who takes long-term monitoring seriously is one who understands that phakic IOL safety extends well beyond the operating theatre.
Phakic IOL results are among the most transformative in ophthalmology, taking patients from functional disability to clear uncorrected vision.
Patients with extreme prescriptions — -15.00 or -20.00 dioptres and above — routinely achieve functional uncorrected vision that allows independent daily living without spectacles. The optical quality of phakic IOLs at extreme prescriptions is significantly better than thick spectacle lenses, which cause minification, barrel distortion, and restricted peripheral fields.
Outcomes depend on the precision of the pre-operative biometry and lens power calculation. Most patients achieve corrected acuity equal to or better than their best spectacle-corrected vision. The consultation covers what is realistically achievable for your specific prescription and anatomy, including any residual refractive error that may require a laser touch-up.
Phakic IOL requires 5–7 days in Thailand, with both eyes typically treated on separate days and multiple follow-up checks.
Plan for 5–7 days. Day 1 covers comprehensive biometric assessment. Surgery for the first eye follows within 1–2 days, the second eye 1–3 days later. Follow-up appointments after each eye check implant position, vault or clearance, and intraocular pressure. Clearance to fly is given once both eyes are stable.
Your care coordinator manages all scheduling, transfers, and follow-up logistics. The surgical quote covers biometric assessment, phakic IOL lenses for both eyes, surgeon and facility fees, post-operative medications, and follow-up appointments. Flights and accommodation are arranged separately, with recommendations provided for hotels near the hospital.
Recovery is rapid — visual improvement is apparent within hours — but the multiple follow-up checks require staying near the hospital. Bangkok is ideal for this. Between appointments, you are free to explore, eat, and relax. Just avoid swimming, dusty environments, and strenuous activity for the first few weeks.
