A surgical technique is described for posterior chamber intraocular lens implantation within the capsular bag with a posterior capsular tear or weakened zonular support. Haptics are compressed before endocapsular insertion, minimizing capsular and zonular stress.

A new method for enlarging a small pupil during cataract extraction is described. The technique is simple and safe, and uses new instruments that reduce or entirely eliminate the need to incise or suture the iris. This method of pupil enlargement can be used for extracapsular cataract extraction and phacoemulsification procedures.

The advantages of continuous circular capsulorhexis and endocapsular (endolenticular, posterior chamber, in situ) phacoemulsification are well recognized. Perhaps the only disadvantage of the phacoemulsification technique is the increased operative time. This report presents a new method for endocapsular phacoemulsification which includes a superiorly decentered circular or oval capsulorhexis and more rapid endocapsular phacoemulsification using a combination of one- and two-handed techniques. The procedure may also be safer since most of the phacoemulsification is performed within the central "safe zone" of the posterior chamber.
This report describes a series of six children who had a retropseudophakic vitrectomy performed via a limbal approach (limbal approach retropseudophakic vitrectomy, LARV). This technique ensures a permanently clear visual axis when performed at the time of cataract/implant surgery and can also be used to excise secondary membranes in patients who have had prior cataract extraction and intraocular lens implantation. A modification of this method permits the retrolenticular opacity in children with persistent hyperplastic primary vitreous (PHPV) to be relocated or excised at the time of cataract or cataract/implant surgery.
