Complications of radial keratotomy: eyes with keratoconus and late wound dehiscence.

Background: Radial keratotomy requires a thorough preoperative examination, including photokeratography, to detect early keratoconus.

Methods: We compared, by light and transmission electron microscopy, the healing process of corneas from two patients after radial keratotomy.

Results: Clinically, one patient had a keratoconus and gained no visual benefit from the radial keratotomy.

[Persistent hyperplastic primary vitreous. Middle-term results of vitrectomy].

In this study, the authors present a homogeneous series of seven children suffering from persistent hyperplastic primary vitreous, in its complete anterior and posterior form. These children were operated by pars plana lensectomy and vitrectomy. The surgical operation was beneficial in every case: not only were there no complications, but the operation also prevented progression towards neovascular glaucoma, vitreous hemorrhages and phtisis bulbi.

[Radial keratotomy: analysis of undercorrected patients, based on 200 successive operations].

The authors present the results of a series of 200 radial keratotomies. there were two anatomical complications, neither of which caused any clinical damage. 83% of patients obtained 5/10 distant visual acuity or more without correction.
