Vision Correction Surgery
At Eye and Retina Surgeons, we offer a comprehensive refractive surgery practice to deal with the whole gamut of refractive errors. These are :
  1. Myopia or short-sightedness; far and away the commonest refractive error seen in Singapore
  2. Astigmatism or ‘san guang’; the second most common refractive error seen here.
  3. Presbyopia or ‘lao hua yan’; the common inability to read in those above 40
  4. Hyperopia or long-sightedness; uncommon.
LASIK has stood the test of time in terms of its success rate and efficacy and we offer it in several modes. It is basically an operation in which a corneal flap is raised and then an excimer laser is used to reshape the cornea underneath after which the flap is replaced. This is like carving a contact lens on the eye.
Before a patient even gets to the operating room though, much important work needs to be done as part of the pre-operative assessment. Only in this way can we assess if a patient’s eye is suitable for Lasik vision correction. This establishes the safety/benefit profile.
An accurate refraction to determine your refractive error is carried out by our fully qualified optometrist before and after pupillary dilatation. Other important measurements are also carried out: of importance is the corneal topography and we have two systems available to do this, the ORBSCAN II from Bausch and Lomb and the PENTACAM from Oculus. Corneal topography shows us the contours and thickness of the cornea so that an optimal treatment plan can be formulated by our doctors. Wavefront measurements using the Zywave aberrometer are also available. Finally a careful examination through the dilated pupil is made to exclude cataract and other retinal problems like retinal holes or detachments. If your LASIK surgeon does not do this, ask him to! Myopic individuals have a higher risk of thin retinas with holes or retinal detachments and it is an essential pre-LASIK examination. We have seen many patients over the years who have had these problems picked up during a thorough pre-LASIK assessment. These retinal problems need to be repaired before LASIK is considered.
Type of LASIK
The eye surgeon will review and check the numbers and plan the type of LASIK: essentially there are five types of LASIK:
  1. Standard plano-scan LASIK: this is the tried and tested, reliable and predictable LASIK procedure and is suitable for most people who have nice, thick corneas and ‘normal’ levels of myopia (eg under -6 or 600 degrees). It is also an economical method.
  2. Aspheric LASIK is the current iteration in LASIK treatment modalities. It gives good quality vision and yet saves on the amount of tissue used.
  3. Tissue-saving LASIK is a very useful form of LASIK because it allows patients with thinner corneas to have full myopic/astigmatic treatments and yet retain enough cornea for structural safety and for possible enhancement LASIK.
  4. Wavefront LASIK is useful in selected patients who have high levels of pre-existing aberrations in their visual system.
  5. ReLEx SMILE is the 3rd generation of laser vision correction. It is based on the flapless SMILE procedure (small incision lenticule extraction) and hence reduces the risk of flap related complications. This offers the potential for fewer transected corneal nerves and more preservation of tissues with consequent reduced incidence of dry eyes.
How is LASIK Performed

Small Incision Lenticule Extraction

ICL phakic intraocular lens in the eye
The implantable contact lens is a type of phakic intraocular lens (PIOL) used in the correction of eyes with high refractive errors, especially if the cornea is thin. PIOL are artificial lenses which are implanted in front of the natural lens of the eye and functions as a “contact lens” within the eye affording high quality (high definition) vision. PIOLs are especially useful in certain patients who are not suitable for which laser refractive surgery like LASIK. At Eye & Retina Surgeons, the Visian Implantable Collamer Lens (ICL; Staar® Surgical Company, USA) is available for patients who require phakic intraocular lens implantation.
The Visian Implantable Collamer Lens (ICL; Staar® Surgical Company, USA) is a one-piece foldable phakic intraocular lens which is implanted just in front of the natural crystalline lens as a day surgery procedure. This PIOL requires a sutureless sub-3 mm corneal incision for insertion allowing fast visual rehabilitation and eliminating the need for hospital admissions. The Visian ICL is able to correct myopia of -3.0 D to -20.0 D (US approval). Toric models of this PIOL are also available. Toric models are able to correct both myopia and astigmatism simultaneously, eliminating the need for subsequent procedures to correct astigmatism.
