Ophthalmol.-1988,23 (6) .- 259 ~ 261 intraoperative use of sticky polymer can effectively reduce the loss of corneal endothelial cells caused by cataract surgery and intraocular lens implantation. Many medical centers use 1% sodium alginate for cataract surgery, but they can be very expensive. Several recent studies have been conducted to find sticky materials that are safe and effective to replace sodium hyaluronate. Methyl cellulose is a glucose-related polymer. It is chemically inert, is not conducive to the growth of microorganisms, can be disinfected, non-pyrogenic, is a viscous synthetic compounds. Three types of methyl cellulose compounds have been approved for medical use, ie, hydroxypropyl methylcellulose
