Retrobulbar block using pentothal as a sedative for ambulatory cataract surgery.
Cataract surgery comprises 80% to 85% of the surgical procedures performed at our ambulatory surgical center. We have developed a safe and effective method of sedation and amnesia for performing a retrobulbar block. We use sodium thiopental, administered intravenously, just prior to the block. We encourage the anesthesia departments of other facilities to consider this relatively simple blocking procedure for the comfort and safety of the patient.

A model intraocular lens.
With so many different kinds of intraocular lenses from which to choose, the cataract surgeon is often faced with a difficult decision--which is the best lens for the patient. Although, there is no perfect intraocular lens, we attempt to delineate several desirable features. These include pliability, inert ultraviolet-filtering lens material, compact design, and posterior concavity to facilitate laser surgery. Successful blending of these features can make a well-tolerated intraocular lens.

The collagen eye patch: a preliminary report.
This study is a preliminary report on the use of freeze-dried-collagen eye patches in the treatment of a selected group of inflammatory eye conditions. The early responses to treatment have been encouraging in cases of allergic conjunctivitis, blepharitis, and pterygium. In addition, the collagen patches have exhibited a significant beneficial effect in the resolution of ectropion.

Neodymium: YAG laser posterior capsulotomy.
Posterior capsule opacification, caused by pearl formation or fibrosis, occurs commonly following cataract surgery. This paper presents results of a study of 367 Nd:YAG laser posterior capsulotomies and discusses both risks and benefits. Specific attention has been given to intraocular pressure (IOP), corneal endothelial cell integrity, and visual acuities. The average maximum induced IOP rise was 1.4 mm Hg and this occurred within one hour of the capsulotomy. The average corneal endothelial cell change was a loss of 7% or 115 cells/mm2. Visual acuity improved to better than 20/30 in 87.5% of patients.

Pseudophakia in children: a review of results of eighteen implant surgeons.
Intraocular lenses are a wise choice in a limited number of traumatic cataracts. It is necessary, however, to evaluate the patient very closely preoperatively to be assured that preoperative problems associated with increased postoperative complication are not present. In the proper patient, these authors feel that implant surgery is indicated. It offers a satisfactory alternative to the occasional patient that would have a functionless or amblyopic eye with a contact lens. Although the patient with a contact lens may see well with the contact in place, many are not able to wear the contact lens long enough during the day to consider it a functional success. These authors stress the use of a lightweight two-loop iridocapsular lens with one stage surgery and a short interval between the development of the cataract and the operation. Contact lenses or aphakic glasses are safe and will suffice with bilateral congenital cataracts. At the present time, further experimentation is necessary to determine if intraocular lens placement in the two-month-old infant with a unilateral congenital cataract will be safe and wil restore vision.

Lens glide in implant surgery.
The lens glide is a disposable, sterile piece of Silastic that is designed to make insertion of intraocular lenses safer and simpler. Since the use of the lens glide has become part of our routine surgical procedure in implant surgery, there has been a notable reduction in vitreous loss and in postoperative corneal problems.
