	Traditional Cataract Operation	Ultrasound Phaco	LASER Phaco
Operating procedure	The eye is cut open and the cataract removed. After implanting the intraocular lens, the wound is stitched up.	Using the ultrasonic vibration needle, through a small puncture wound, the cataract is broken into small pieces and sucked out. After that, the intraocular lens is implanted.	Using the laser fibre, through a small puncture wound, the cataract is broken into small pieces and sucked out. After that, the intraocular lens is implanted. No stitches required.
Sensation	Painful	Slight discomfort	Painless
Length of operating time	45mins	15 to 20mins	15 to 20mins
Recovery period	About one to three months	About one week	Few days (less than one week)
Incident of blindness	1-5%	0.1%-2%	0.1%-1%
Complication	Ocular inflammation, infection, hemorrhage, retinal detachment and glaucoma.	Less complications	Much less
Remarks	Patient has to wait till the cataract matures or hardens so that the operation can be carried out with ease. However, over-mature cataract can cause glaucoma and inflammation which leads to permanent blindness	The earlier the cataract is detected and the easier it is to be sucked out. However, since it generates heat, it may burn ocular tissues.	The earlier the cataract is detected and the softer it is, the better the results would be. The laser is more concentrated and much less energy used, therefore causes less damage to the ocular tissues. The recovery period is shorter.
