Methylcellulose in extracapsular surgery with intraocular lens implantation.

We present our experience in 28 consecutive operations using methylcellulose 2% in implantation surgery. Visual acuity of 20/40 or better was obtained in 96% of the cases. This solution is tolerated well by the human eye, protects the endothelium, maintains the depth of the anterior chamber, and facilitates the insertion of the intraocular lens. We have had no significant increases in intraocular pressure or excessive intraocular inflammation. In routine cases of implantation surgery, there is no reason to use more expensive viscoelastic substances. Because this substance is universally available, it can be prepared easily for intraocular use, and it is inexpensive making its use in developing countries strongly recommended.
