Hong Kong Baptist Hospital's Laser Refractive Surgery and Cataract Centre has a dedicated team of professionals and a comprehensive range of facilities including a laser refractive surgery theatre, cataract surgery rooms, an optometric room, an ophthalmology consultation room and an audio-visual information centre. The Centre also runs regular public seminars on laser refractive surgery.

LASIK (Laser Assisted In-Situ Keratomileusis) is the quickest and most stable method to correct refractive problems. During the surgery, your eye is anaesthetised and an eyelid holder is placed into your eye to prevent blinking. An instrument is used to cut a flap in your cornea, following which a computer-controlled laser beam vaporises a portion of the corneal tissue to change the shape of the cornea. Finally, the flap is put back in position without any stitches. The benefits of LASIK include less surface area to heal, less risk of scarring and corneal haze, reduced post-operative discomfort and most importantly, a quicker visual rehabilitation (often within a day or so).

IntraLase is the contemporary method used in the first part of the LASIK procedure. It makes LASIK safer by replacing the traditional blade with a femtosecond laser, minimizing flap complications and improving the safety and efficacy of LASIK as a result.

IntraLase LASIK

You are likely to be suitable for LASIK if:

	You have reached the age of 18
	You have healthy eyes
	Your eyesight has not changed significantly over the last year

The Centre is equipped with state-of-the-art instruments all approved by the U.S. Food and Drug Administration (FDA). 1. Zyoptix Diagnostic Workstation It combines data from two different types of diagnostic equipment. Zywave Aberrometer It measures the eye from the centre to the periphery of the pupil and allows doctors to calculate the difference between your day- and night-time vision. Orbscan IIz Topographer It analyses the physical shape of your cornea.

Data collected from the aforesaid examinations will be input into the treatment card for surgical use. 2. Technolas 217P Excimer Laser It uses cool ultra-violet light with the latest flying spot technique to track tiny eye movements and to guide the laser during the LASIK procedure. With the innovative Advanced Personalised Technology (APT) and Dynamic Rotational Eyetracker System (incorporating iris-recognition software), effectiveness of LASIK is further enhanced.

Public seminars on laser refractive surgery are held regularly, please call the Centre for appointment.

The structure of human eye is similar to that of a camera. When light rays enter the eyes, they pass through the cornea and the lens. The cornea and lens focus an image automatically onto the retina, on which the optic nerve transmits the image to the brain.

Cataract means cloudiness of the lens. If the degree of cloudiness is getting more severe, it may obstruct the passage of light rays, vision will then become blurry. Hyper mature cataract may result in glaucoma and uveitis, or even blindness.

Cataract is mainly caused by natural degenerative process. Other causes include inheritance, trauma, diabetes mellitus and certain kinds of medication consumption.
Blurring Hypersensitivity to strong light Dimmer color sensation Poor light sensation when reading Frequent change of refractive error

With the latest technology, Phacoemulsification, and the use of foldable IOL, the size of the surgical wound has been largely reduced. During the surgery, a small ultrasound probe is inserted into the eye through a very small wound. The ultrasound emitted from the probe will break down the cataract into small pieces, which are then absorbed by one of the orifices on the probe. Finally, the IOL is implanted.

Current Choices of Intraocular Lens

The modern intraocular lens (IOL) is not only focusing light but also filtering away damaging light from the eye.

Traditional IOL can only filter ultraviolet light. The newly developed blue filtering IOL can filter high frequency blue light, which possesses higher energy, as well as ultraviolet light. This new filtering function, works like the natural lens, may further reduce the chance of retina damage from blue light.

Intraocular Lens with Specific Refractive Functions

The latest IOL allows some patients to achieve spectacle independence after operation. For example toric IOL allows correction of astigmatism together with myopia or hypermetropia in the same setting. Multifocal IOL improves near, intermediate, as well as distant vision in some presbyopic patients. You may discuss with your eye doctor the available options to suit your needs in daily living.
