We have devised a new type of pterygium surgery, based on the principle of biological contact inhibition, involving the use of a 0.5-millimeter-wide pedicle autoconjunctival strip placed at the corneal limbus. Over a period of 2 years, the procedure has been performed in 56 eyes of 52 patients, 39 to 74 years old (mean, 57 ± 9 years), with primary pterygium. After an average follow up of 34 ± 6 months (range, 20 to 40 months), the pterygium recurred in six (10.7%) of the 56 eyes. There were no other significant postoperative complications. Although our method has the disadvantages of being somewhat complicated and involving a fair amount of suturing, the relatively low rate of recurrence achieved is encouraging.

Aims/background-To clarify whether intraocular lens (IOL) implantation in the human eye aVects the durability of polymethylmethacrylate over an average period of 10.9 years. Methods-Shearing stress and extent of damage following neodymium (Nd):YAG laser application to 18 study and 12 control optics were examined. Results-No significant diVerence was found between the study and the control IOLs in shearing stress and extent of damage following Nd:YAG. Conclusion-An average 10.9 years' implantation in humans does not aVect either the shearing stress or extent of damage following Nd:YAG shots of polymethylmethacrylate.
