Photorefractive keratectomy (PRK) is a type of laser eye surgery. PRK uses an ultraviolet laser to reshape the cornea (outer surface of the eye). PRK can correct astigmatism, nearsightedness, and farsightedness. Unlike LASIK, PRK does not create a flap in the eye. Although no surgery is completely safe, PRK has less complications or side effects than LASIK. Some patients who can not have LASIK may be able to get PRK. PRK is especially preferred over LASIK for people with high prescriptions, thin corneas, and people who are more likely to get eye injuries, such as athletes or police officers. Potential side effects or complications include seeing haloes, starbursts, or glare, corneal haze, dry eye, infection, blurry vision, double vision, and the continued need for glasses or contact lenses. Side effects are more likely if an old or obsolete laser is used, which many clinics still use. Side effects are usually temporary but may become permanent. Some temporary side effects may be caused by the eye drops used, and not the surgery itself.
The surgeon gives anesthetic drops in each eye, to prevent the patient from feeling pain. The epithelium (outer layer of the cornea) is brushed off, and the surgeon uses a laser to remove small amounts of the cornea, changing its shape. Mitomycin C is then applied to the eye, which helps prevent corneal haze. A bandage contact lens is then placed over the eye, and the epithelium grows back behind the contact lens. Vision will be blurry for a few days, and there will be some pain and discomfort. The recovery period is longer and more painful than LASIK. Several sets of eye drops, applied several times each day, are necessary for at least a week or longer. After about a week, the epithelium has grown back, and the surgeon removes the contact lens. The patient must sleep with a protective shield over the eyes until the contact lens is removed.
Octopus card
The Octopus card is a reusable contactless stored value smart card for making electronic payments in Hong Kong. Started in September 1997 to collect fares for the MTR, the Octopus card system is the second contactless smart card system in the world, after the Korean Upass, and has been widely used for all public transport in Hong Kong. It led to the development of Oyster card in London.
"Baat Daaht Tùng" (Cantonese Pronunciation) translates as "eight-arrived pass" (in Chinese it was accepted as "go-everywhere pass"), where "Baat Daaht" may translate as "reaching everywhere". It was selected by the head of the MTR, the parent company of Octopus Cards Limited, in a naming competition held in 1996.

Breast augmentation
Breast augmentation is a surgical procedure used to increase the size of the breasts.
Usually, implants are used, but another technique called fat grafting is sometimes used. The size increase can be as small as one cup size, or as large as 10 cup sizes or more.
The larger the increase, the greater the risk of complications. Complications may include leaking of the implants, which may require the implants to be replaced. With larger breasts the whole weight balance of the body is changed, which may cause stress to the muscular and skeletal systems.
A surgical implant is either an implant filled with saline-solution, or an implant filled with silicone-gel. The fat-graft transfer uses grafts of adipose fat tissue from the woman’s own body. A full assessment of this method is not yet available. The method does not allow for the huge size increase possible with implants, and slim women may not have enough fat tissue to allow the method to be used.
Implants are inserted into the breast and filled with silicone or a saline solution. This is the most common method of augmentation.
Yarn-like polypropylene string is inserted into the breast, where it irritates the breast, causing it to fill with fluid. Polypropylene string produces very large size increases, often well over 20 cup sizes. It has a very high complication rate and is now banned in the United States and many other countries.
Fat is removed with liposuction from an area of the body where it is not desirable. The fat is then cleaned and injected into the breast.
