Implantation of posterior chamber lens in the absence of capsular and zonular support.

We have developed surgical techniques for implanting a posterior chamber lens in the absence of capsular and zonular support by securing both haptics of the posterior chamber lens to the sclera at the ciliary sulcus with 10-0 prolene suture. These techniques have been successfully performed and have produced good visual results in six monocularly aphakic patients who had contact lens intolerance and/or contraindications to anterior chamber lens implantations. In consideration of the high incidence and the great variety of complications associated with anterior chamber lenses, these newly developed surgical techniques will be a useful alternative to anterior chamber lenses, even in patients who do not have definite contraindications to anterior chamber lens implantations.

A new surgical technique for posterior chamber lens fixation during penetrating keratoplasty in the absence of capsular or zonular support.

A new technique has been developed to implant or exchange an anterior chamber or iris supported lens with a posterior chamber lens during penetrating keratoplasty. The posterior chamber intraocular lens is suspended by suturing the haptics into the ciliary sulcus rather than to the iris.

Pigmented corneal implants: a surgical treatment for iridectomy related optical complications.

Initial evaluation in rabbits demonstrates that corneal implants made from prolene and nylon sutures flattened into strips appear promising as a means of covering diplopia or glare-inducing iridectomies. Two-month follow-up studies showed the implants to be well tolerated in the corneal stroma. Results of the studies suggest that black prolene films of 50 to 70 micrometers in thickness, contoured to follow the corneal curvature, would be the ideal configuration for such implants.
