Lasik Surgery In Singapore
Back in the year 2000, ophthalmologists in Singapore considered it a success to be able to achieve a 20/20 uncorrected visual acuity after refractive surgery. Further research in the field has helped ophthalmologists in Singapore realize that 20/20 was not a representation of perfect vision and stepped forth to further improve these results.
Ever since then, the goals in LASIK Singapore were three-fold:
1. Achieving a higher quality 20/20 vision in patients, with less glare and halo at night, after the surgery.
2. Achieving vision in patients that exceeds 20/20 after surgery.
3. Achieving the possible use of LASIK to correct aberrations and refractive errors in eyes that underwent less-than-optimal refractive procedures previously.
Developments in LASIK surgery have been aiming to reduce aberrations and irregularities in the cornea. This way, common postoperative side effects of LASIK such as double vision when viewing with one eye, glare and halo will be reduced.
Limitations Of Past Processes
In the past, when a phoropter was used, to measure the optical characteristic of the eye, it could only be described with only three numbers, namely the axis, cylinder and sphere. Unfortunately, this was too generic and simple.
Super Vision By Custom Ablation
The emergence of aberrometers and wavefront sensing devices in the field of LASIK in Singapore made it possible to measure wavefront that various structures in the eye tend to create. All the structures in the eye tend to give rise to aberrations, and their cumulative sum gives the complete optical aberration of the eye. It is still unknown which eye structures are responsible for which aberration component, but it has become possible to measure the total aberration of the eye.
LASEK & Epi-LASIK
LASEK (Laser-assisted subepithelial keratectomy) and Epi-LASIK represent the latest developments in LASIK surgery in Singapore. LASEK is similar to Photorefractive keratectomy (PRK), i.e. it does not involve the use of a blade. Instead, it involves the use of an alcohol solution prior to laser ablation to loosen the corneal epithelial or the surface of the outermost layer of the cornea. After the completion of photoablation, the ophthalmologist repositions the corneal epithelial over the ablated area.
Epi-LASIK is probably the most advanced form of LASIK in Singapore, and a proof of the development that has been taking place in the field of refractive surgery in Singapore. Moreover, much more research needs to be carried in the application of wavefront technology. As mentioned, in the past, the axis, cylinder and sphere were the only 3 numbers with which the optical characteristic of the eye could be described. However, with wavefront technology, ophthalmologist in Singapore managed to learn that the use of just 3 numbers to describe the optical characteristic of the eye is not too generic and simple. Currently, major evolution is taking place in the field of refractive surgery and LASIK in Singapore, and many more developments will eventually be made in ophthalmology and optometry in Singapore.
