Refractive & Intraocular Comparison: iLASIK / Femto-LASIK vs No-Touch TransPRK vs Trifocal Smart Lens
Selecting the optimal vision correction protocol based on corneal pachymetry, patient age, presbyopia, and diopter profile.
| Clinical Parameter | iLASIK / Femto-LASIK | No-Touch TransPRK Laser | Trifocal Smart Lens (IOL) |
|---|---|---|---|
| Primary Clinical Indication | Ages 18–42 with adequate corneal thickness seeking rapid myopia, hyperopia, or astigmatism correction | Thin corneas, dry-eye predisposition, or contact athletes/professionals requiring flapless stability | Ages 40+ with presbyopia (reading + distance glasses), extreme refractive errors, or early cataract |
| Core Technology & Biomaterial | Alcon WaveLight® FS200 bladeless femtosecond flap + EX500 Contoura® topography-guided excimer | Zero-instrument-contact single-step transepithelial excimer ablation + therapeutic bandage lens | Alcon® AcrySof® PanOptix® or Carl Zeiss® AT LISA® tri trifocal / toric intraocular lens |
| Anesthesia & Procedural Protocol | Anesthetic eye drops only (10–15 minutes total for both eyes, zero hospital stay) | Anesthetic eye drops with zero suction ring or blade contact (seconds of laser delivery per eye) | Topical anesthetic drops via micro-incision phacoemulsification (10–15 min per eye, outpatient) |
| Clinical Recovery & Return to Routine | Crisp functional vision the very next morning (3–4 day Istanbul itinerary) | 3–4 days epithelial healing with protective soft lens; progressive clarity over 5–7 days | 4–5 day Istanbul itinerary; shield removed the next morning for near, intermediate, and far focus |
| Structural Longevity & Certification | 22,000-point personalized corneal remodeling on an FDA-approved 1050 Hz eye-tracked suite | Preserves maximum residual stromal biomechanical strength without a corneal flap interface | Lifetime optical clarity permanently preventing cataracts; serialized FDA & CE Optical Implant Card |

Penetrating Keratoplasty (PKP) at ONE CLINIC
At One Clinic, we offer Penetrating Keratoplasty (PKP), a specialized surgical procedure that replaces damaged or diseased corneal tissue with healthy donor tissue to restore vision.
PKP, also known as corneal transplantation, is an extremely effective treatment for conditions such as corneal scars, keratoconus, corneal dystrophies, and corneal degeneration.
Our Penetrating Keratoplasty services include:
We begin with a comprehensive consultation to assess your eye health, measure visual acuity, and determine whether Penetrating Keratoplasty is the appropriate treatment option for you. During this consultation, our experienced ophthalmologists will review your medical history, perform a thorough eye examination, and address any questions or concerns you may have about the procedure.
Using advanced imaging technology and diagnostic tests, we carefully evaluate the condition of your cornea and determine the extent of damage or disease progression. This assessment helps us tailor the treatment plan to your specific needs and enables us to achieve the best possible outcomes.
For Penetrating Keratoplasty, donor corneal tissue is sourced from eye banks and carefully screened for quality and compatibility. Our team ensures that the donor tissue is compatible with your eye and meets the highest standards of safety and efficacy.
Penetrating Keratoplasty is performed in a sterile operating environment under local or general anesthesia. During the procedure, our experienced eye surgeons remove the damaged or diseased corneal tissue and replace it with healthy donor tissue. The donor tissue is secured in place with small sutures to support the healing and integration process.
Following Penetrating Keratoplasty, we provide detailed post-operative care instructions to promote healing and reduce the risk of complications. Our team monitors your recovery and schedules follow-up appointments to adjust your treatment plan as needed.
Vision may be blurred immediately after Penetrating Keratoplasty, but most patients experience significant improvement in visual acuity over time as the eye heals and adapts to the new corneal tissue. Our team will work with you to optimize your visual outcomes using prescribed glasses or contact lenses.
Long-Term Follow-Up:
Following Penetrating Keratoplasty, regular eye examinations and monitoring are essential to maintain the health and stability of the transplanted cornea. Our team will provide ongoing care and support to help keep your eye health and visual function at optimal levels.
At One Clinic, we are dedicated to providing exceptional care to patients undergoing Penetrating Keratoplasty and achieving the best outcomes. Our experienced ophthalmologists, state-of-the-art facilities, and commitment to excellence make us a trusted choice for corneal transplantation and vision restoration.
Regain your vision and improve your quality of life with Penetrating Keratoplasty. At One Clinic, let our advanced corneal transplant techniques help you see the world more clearly and confidently.
