Refractive Surgery (LASIK and Advance Surface Ablation)
Refractive surgery is the term used to describe surgical procedures that correct refractive errors and help patients to be independent or less dependent of spectacles and contact lenses.
Since LASIK and refractive surgery started in the 1990s, and was eventually offered in Singapore in 1996, the advancement in technology for these surgeries have improved remarkably over the years.
Besides the technology, cornea and refractive specialists have also come to learn and understand the behavior of the cornea and outcome of such refractive surgeries a lot more.
The advancement in laser technology, treatment, diagnostic and the deeper understanding of the cornea and refractive surgery makes LASIK surgery effective, predictable and safe.
The most popular refractive surgery is the laser procedure known as Laser-Assisted In Situ Keratomileusis surgery (LASIK). The surgery is performed with anaesthesia using eye drops. It involves the use of femtosecond laser to create a cornea flap, and then shaping a thin layer of corneal tissue with use of an excimer laser. At the end of the surgery, the flap is replaced back into place. The goal of LASIK is to improve vision to the point of not being dependent on spectacles or contact lenses, or to the point of wearing thinner spectacles.
Advance Surface Ablation
Advanced Surface Ablation (ASA) comes in form of PhotoRefractive Keratectomy (PRK) / TransPRK / Epi-LASIK / LASEK. The surgery is performed with anaesthesia using eye drops. It involves removal of the epithelial layer of the cornea with the use of alcohol / epi-blade / laser and subsequently the use of an excimer laser to shape a thin layer of corneal tissue.
Why choose JL Eye Specialists for your LASIK surgery?
At JL Eye Specialists, Dr Jimmy Lim is an experienced ophthalmologist and eye surgeon with more than 18 years of practice in clinical ophthalmology. He was fellowship-trained at the prestigious Baylor College of Medicine in United States of America under the tutelage of Professor Douglas Koch, specializing in both laser refractive surgeries (LASIK) and corneal surgeries.
Dr Jimmy Lim is driven to provide optimal eye care to all his patients. He meticulously integrates advanced technology know-how and detailed corneal assessments, providing patients a better understanding of their suitability for LASIK surgery.
Coupled with the use of advanced laser technologies such as the SCHWIND AMARIS 1050RS and the 5th generation iFS Intralase femtosecond laser, Dr Jimmy Lim’s treatment provides for highly effective and precise outcomes with enhanced safety and comfort for his patients.
As not all patients are suitable for LASIK and refractive surgery, it is important to consult with Dr Jimmy Lim for a suitability assessment. Based on your pre-op assessment, you will be recommended the most suitable method of surgery.
Advanced Technologies for LASIK and Refractive Surgery Diagnostics and Management
The Galilei G4 combines Placido disc–based topography and Dual-Scheimpflug tomography in one unit. This combination allows the device to provide complete analysis of both the anterior and posterior corneal surface for comprehensive screening required for refractive surgery such as LASIK, PRK, ASA, etc. all in one measurement session.
The Galilei G4 topography function accurately measures the anterior curvature of the cornea where it precisely detects anterior surface irregularities and tear film quality.
The Galilei G4 tomography function precisely measures pachymetry and elevation data with 3D anterior chamber analysis. The ray-traced posterior corneal surface data detects any protrusion or asymmetry in early stages of corneal diseases.
The 5th generation Intralase iFS Laser allows highly customizable LASIK flap to be created in as fast as 12 seconds. The iFS Laser draws together two major innovations in flap architecture: the inverted bevel-in side cut and elliptical-shaped flaps. The inverted bevel-in side cut increases the stability and strength of the corneal flap, while elliptical-shaped flaps allow maximal stromal bed exposure for ease of treatment.
The iFS Laser provides the idyllic mixture of benefits such as: minimal tissues disruption of the cornea, firmer flaps, lesser instances of complications with a quicker recovery of vision.
The intelligent SCHWIND CAM module ORK-CAM allows highly precise planning of patient’s refractive laser treatment.
Two types of treatment profiles are available to cater to different patients’ needs, enhancing post-operative vision quality.
The ORK-CAM calculates the ideal centration and size of the laser treatment zone based on the eye parameters and treatment method. This helps to minimize tissue ablation to ensure patient safety, at the same time achieving stable visual outcomes.
