J Cataract Refract Surg 1997, 23:657-663. This article is important because it presents a technique that significantly helps control the difficult problem of secondary cataract in infants and children, and also because it provides new information that contradicts reports reviewed here last year by these authors (Kohnen T et al.: Secondary cataract formation following pediatric intraocular lens implantation: 6-month result. German J Ophthalmol 1996, 5:171-175) and by Howard Gimbel (Posterior capsulorhexis with optic capture in pediatric cataract and intraocular lens surgery. Ophthalmology 1996, 103:11).

The authors suggest that "relative bioadhesion between the lens capsule and the IOL" may explain why the AcrySof IOL has less decentration and less secondary cataract than PMMA or silicone IOLs.
11. 11 Linnola R: Sandwich theory: bioactivity-based explanation for posterior capsule opacification. J Cataract Refract Surg 1997, 23:1539-1542. This author theorizes that bioactive bonding (similar to the bioadhesion proposed by Ursell et al. [10]) explains the adhesion of the lens capsule to the AcrySof IOL. He proposes that "perhaps the ideal IOL is not bioinert with good biocompatibil" ity but rather bioactive with good biocompatibility."

J Cataract Refract Surg 1997, 23:1521-1527. The studies by Tetz et al. and Pande et al. are important in that they provide methods for precise measurement of posterior capsule opacification, necessary for determining efficacy of methods for preventing posterior capsule opacification.

23. 23 Caballero A, Salinas M, Marin J: Spontaneous disappearance of Elschnig pearls after neodymium:YAG laser posterior capsulotomy. J Cataract Refract Surg 1997, 23:1590-1594. The authors describe spontaneous disappearance of Elschnig pearls, a phenomenon commonly recognized but apparently not previously noted in the literature. It is important to good clinical practice, as well as for medicolegal reasons, that all surgeons recognize that this can happen, with or without prior laser posterior capsulotomy.
