A new method for cataract removal by phacoemulsification in impaired lenticular joints consists in fixation during surgery of the anterior lenticular chamber along the edge of the capsulorrhexis by 4 retractor hooks and subsequent implantation of a soft intraocular lens. The operation was performed in 6 patients with cataracts of different types complicated by subluxation of the lens. The operation did not involve such complications as vitreous prolapse or displacement of the incompletely dislocated lens. All operations were finished with complete evacuation of lenticular mass and implantation of soft silicone intraocular lenses. The proposed method widens the category of patients in whom modern phacoemulsification can be used.

Rubinstein-Taybi syndrome is a constellation of clinical findings characterized by mental and motor retardation, broad thumbs and broad first toes, typical facies. Ocular and adnexal abnormalities are quite common and include antimongoloid slant of the palpebral fissures, epicanthal folds, congenital obstruction of the lacrimal excretory system, ptosis, strabismus, congenital cataract and congenital glaucoma. The authors describe the case of a 1-year-old male with the Rubinstein-Taybi syndrome associated with unilateral congenital glaucoma. The case emphasizes the importance of detailed complete ocular examinations in patients with Rubinstein-Taybi syndrome, and also highlights the occurrence of ocular abnormalities rarely associated with this disease.

Results of removal of a transparent lens in high myopia are analyzed. The operation was performed in two stages according to V. S. Belyaev and T. S. Ilyina. The second stage of the operation (lens extraction) was performed by the extracapsular method, which prevented vitreous prolapse into the anterior chamber in all cases and ruled out the possibility of detachment of the posterior plate of the vitreous and retina. Simple technique of the operation, good remote results, no need in expensive instruments or equipment recommend this operation for any ophthalmological department performing extracapsular cataract extractions.

Fifty-five closed anterior manual vitrectomies were carried out in patients with vitreal complications after cataract extraction with implantation of posterior-chamber intraocular lenses. The results indicate high efficiency of anterior vitrectomy as a method for surgical treatment of sluggish uveitis, keratopathy, macular edema, secondary glaucoma, developing as a result of vitreous prolapse during implantation of the posterior-chamber intraocular lens. The operations were performed through transscleral and corneolimbic accesses. No cases of intraocular lens dislocation occurred.

Multiple ocular associations with Duane syndrome have been reported as summarized by DeRespinis et al. The most frequently noted include nystagmus, anisocoria, ptosis, optic nerve colobomas, and epibulbar dermoids. Less encountered abnormalities are optic nerve hypoplasia, heterochromia, and congenital cataract. To our knowledge, no reports of associated congenital glaucoma exist in the literature. We report a 10-year-old patient with bilateral Duane syndrome and bilateral congenital glaucoma who we have monitored for 7 months after birth.

In a university ophthalmology department, a cluster of postoperative diplopia and ptosis cases occurred in the initial 3 months after hyaluronidase (Wydase) became unavailable for use with injection anesthesia. These cases suggest that hyaluronidase, when used with injection anesthesia, may protect extraocular muscles and nerves from the toxic effects of local anesthetic agents. The spreading action of hyaluronidase facilitates uniform diffusion of anesthetic agents. This prevents elevated extracellular tissue pressure, a cause of ischemic damage to extraocular muscles or nerves. Hyaluronidase may also prevent focal accumulations and concentrations of local anesthetic agents, which at high enough levels may cause myotoxic or neurotoxic damage, fibrosis, and contracture of extraocular muscles or nerves.

Blepharoptosis is a well-documented complication of cataract extraction and other ocular procedures. Few authors have described the surgical findings and outcomes of postcataract blepharoptosis repair. The authors present a review of the causes of postcataract blepharoptosis with emphasis on both clinical findings and recommendations for treatment on the basis of their experience with 13 eyelids in eight patients over the past 10 years. They found that all patients had either partial or total disinsertion of the levator muscle from the tarsal plate. Of the eight patients in this series, five had bilateral blepharoptosis after bilateral cataract extraction. Although a multifactorial cause for postcataract blepharoptosis is commonly assumed, the authors propose that the mechanical forces of intraoperative traction on the levator aponeurosis during cataract surgery are the primary cause. This is further supported by their operative findings in the five patients who developed bilateral ptosis after bilateral cataract extraction. All eyelids in this series were repaired by levator muscle advancement and attachment to the tarsal plate with favorable outcomes and no recurrences during a 1-year follow-up. The importance of Hering's phenomenon of equal innervation is also discussed as it applies to bilateral and to apparent unilateral blepharoptosis. The authors propose "Hering's test" as an important indicative study in the preoperative evaluation of all patients with eyelid ptosis.

The Dubowitz syndrome is a rare, autosomal recessive disorder including intrauterine growth retardation, craniofacial abnormalities, mental retardation and eczematous skin eruption. Ocular problems occur in about 20%: strabismus, blefarophimosis, ptosis, telecanthus and epicanthal folds being the most frequent ones. We present a three years old girl, diagnosed with Dubowitz syndrome, with sudden visual loss due to bilateral cataract.

Iris prolapse is a rare complication after small incision cataract surgery. We looked at the possible operative and perioperative factors that might have contributed to this complication in 2 of our patients and in another 10 patients identified through a national questionnaire survey. The details of 12 cases of iris prolapse following small incision cataract surgery are presented. Since iris prolapse may occur in small incision cataract surgery, notably in the presence of certain predisposing factors, extra diligence is required in wound construction and closure in high-risk patients.

Flexible nylon iris retractors are a useful adjunct to cataract surgery in cases of small pupil. We present a modification of the standard technique. Instead of approaching the square-shaped pupil formed by iris retractors from the side, we recommend an approach anterior to 1 of the retractor hooks. From the surgeon's viewpoint, the pupil goes from a square shape to a diamond shape. This modification minimizes the likelihood of iris prolapse and iris damage during phacoemulsification and increases the workspace for the phacoemulsification needle.
