The extracapsular cataract extraction with posterior chamber intraocular lens implantation (ECCE with PC IOL) was performed on 113 cases (120 eyes) with senile cataract. Half a year after the surgery, uncorrected visual acuity of 0.5 or better was achieved in 65.83%; corrected visual acuity of 0.5 or better in 93.33%, 1.0 or better in 82.50%. The intraoperative complications included vitreous prolapse, residual corte, iridodialysis and Descemet's membrane stripping. The postoperative complications were opaque posterior capsule, iris synechiea, IOL dislocation. The post-operative visual acuity and complications of the outpatient surgery was not significantly different compared to inpatient ECCE with PC IOL. The results showed that outpatient cataract surgery is safe. The advantage and disadvantage of outpatient IOL implantation were discussed, and some measures to popularize this operation for outpatient were recommended.

Complications associated with the intraocular lenses (IOL) implantation can be classified into 3 groups: intraoperative, early and late complications. Some of the complications have to be treated at once, otherwise the condition may deteriorate and lead to the occurrence of various secondary complications. One of the intraoperative complications during the IOL implantation can be the impairment of the corneal endothelium which occurs due to the inadequate size of the incision. A part of the IOL loop can remain incarcerated in the corneo-scleral wound during surgery. A strong choroidal hemorrhage may occur, as well as the shallowing of the anterior chamber. Iridodialysis may appear as a consequence of the implant manipulation. IOL can also be subluxated or luxated anteriorly or below the sclera. All of these complications should be promptly attended to. Early postoperative complications that should be treated as soon as possible are the occurrence of the pupillary block, shallow anterior chamber, secondary glaucoma, choroidal detachment, corneal edema and postoperative iritis. Besides the corneal edema, late postoperative complications include the formation of secondary cataract, the occurrence of cystoid macular edema and retinal detachment. The treatment of some of these complications can be delayed for a certain period, while other require the immediate treatment and correction. In this work the author presents his results, the complications encountered in different stages of the IOL implantation, and the immediate interventions that were carried out.

A technique is described for performing full-thickness glaucoma filtering operation from within the anterior chamber. The procedure utilizes an automated trephine, designated the "trabecuphine," that is capable of simultaneous cutting and irrigation. The trabecuphine is brought into the anterior chamber through a limbal incision 180 degrees away from the planned filter site. The trephine is passed across the anterior chamber, above the iris, and into the angle to perform the sclerotomy. This procedure was performed successfully in 13 eyes of seven cynomolgus monkeys. Complications included two small hyphemas that cleared completely. Other complications such as flat anterior chamber, corneal damage, iridodialysis, conjunctival buttonhole, and cataract formation did not occur. Internal scleral trephination may offer another alternative in the surgical management of patients with intractable glaucoma.

A 44-year-old woman sustained a severe left eye contusion from the explosion of a plastic bottle containing fermented orange juice. This resulted in extensive iridodialysis, posterior crystalline lens dislocation, and intractable glaucoma. Eleven days after the injury, combined surgery of trabeculectomy with mitomycin-C, pars plana vitrectomy, lens removal, iridodialysis repair, and scleral-fixated intraocular lens implantation under general anesthesia was performed. Intraocular pressure (IOP) was under control until 5 weeks postoperatively; glaucoma implant surgery was then performed. At the last follow-up 15 months after the combined surgery, best corrected visual acuity was 20/50 and IOP was 15 mm Hg without medication. Combined surgery can be considered a safe, effective option in the management of severe eye trauma in selected cases.

In order to determine the factors related to the worse final visual outcome following nonperforating traumatic hyphema, the clinical characteristics of 18 patients with visual outcome of 0.1 or worse were compared with those of 166 patients with visual outcome of 0.15 or better. The presence of posterior segment injuries such as macula edema, retinal hemorrhage, epiretinal membrane, and choroidal rupture were significant factors of a poor final visual outcome (P < 0.01). The presence of anterior segment injuries such as corneal blood staining, traumatic mydriasis, iridodialysis, cataract, and lens subluxation had significant predictive factors on a poor final visual outcome and the concurrent posterior segment injuries were more frequent in these patients. Initial visual acuity of 0.1 or worse, glaucoma, vitreous hemorrhage, and eyelid laceration were also significant associations of a poor final visual outcome (P < 0.05). Patients with initially larger hyphema (grade I or more vs microscopic) and older age group (16 years or more vs 15 years or less) tended to have poor final visual acuities. Rebleeding was not associated with significant deterioration in visual prognosis. We conclude that the posterior segment injuries seem to be directly related to a poor visual outcome rather than the occurrence of secondary hemorrhage.

During cataract surgery, the iris of an 83-year-old woman was strongly sucked into the phacoemulsification tip twice, resulting in severe iridodialysis. The dehisced iris was sutured to the sclera using double-armed 10-0 polypropylene on a long curved needle. Intensive suction of the iris by the phacoemulsification tip can lead to severe iridodialysis. Machine setting parameters, particularly flow rate, should be lowered after the first iris suction to avoid further iris damage.

We describe a closed-system technique of iridodialysis repair using a 22.0 mm, plastic handled, 27 gauge straight needle with a hole 1.0 mm proximal to the tip. The distal hole is suitable for passage of 9-0 or 10-0 mm polypropylene or nylon sutures. The technique was effective in 8 patients with traumatic iridodialysis in the upper and inferior temporal quadrants.

During routine physical examination, a five-year-old male rhesus macaque (Macaca mulatta) was observed to have gaps in the right iris. Ophthalmic examination revealed inferior and superior iridodialysis with an anterior cortical cataract. The optic nerve head and fundus were normal. Uninvolved areas of the iris and anterior-chamber angle were normal on the basis of results of gonioscopy. Tonometry revealed normal intraocular pressure. The cause of the iridodialysis in this monkey's eye was not known. The animal had been housed individually since arrival due to requirements of the research protocol. Although the concomitant cataract supports a traumatic cause, there was no history of cranial or other ocular injuries. Trauma from fighting through the cage walls, self-trauma or falling inside the cage while under sedation cannot be ruled out. Multiple hematologic evaluations disclosed no abnormalities. This animal did not manifest behavioral abnormalities or any indication of pain. Therefore, treatment was not initiated. Intraocular pressure continues to be monitored at least semiannually.

Phacoemulsification with intraocular lens (IOL) implantation was performed in the right eye of an 84-year-old woman using a small clear corneal incision. Ten weeks after surgery, the patient fell, which caused traumatic iridodialysis and hyphema with expulsion of the iris through the surgical corneal incision. Apart from a transient rise in intraocular pressure, no other complication was identified and the visual acuity returned to 20/20 within 2 months. The IOL remained in situ and undisturbed in the capsular bag, and the retina remained flat, suggesting that an IOL in the capsular bag may provide a stable barrier to prevent tissue loss from the posterior segment.

We present a case of bilateral eye injury caused by a high-pressure water jet from a fire hose. Eye injury secondary to high-pressure water jets are relatively rare, but invariably result in severe damage to all ocular structures. A 51-year-old woman was admitted to our ophthalmologic department for treatment following a direct hit in the face by a water jet from a fire hose from a distance of about one meter. The patient had bilateral extensive eyelid edema and ecchymosis, conjunctival chemosis with hemorrhage, vitreous hemorrhages in the right eye and iridodialysis with hyphema in the left eye, a transient decrease in intraocular pressure, bilateral superior commotio retinae with macular edema, and bilateral impairment of vision. The patient was treated with topical corticosteroids. Four months later she was re-admitted to our department for surgical repair of iridodialysis in the left eye. Iridodialysis had affected the entire superior nasal portion of the iris, and the pupil was displaced downward temporally. The iris partly obscured the visual axis. After surgical repair the visual axis was free. At a follow-up examination two years later, the ocular findings were the same. The best corrected visual acuity was 0.1 in the right eye and 0.3 in the left eye. Visual impairment was a consequence of permanent posttraumatic posterior fundus changes, particularly of the macula in both eyes. Intraocular pressure was within normal limits in both eyes. Injuries caused by high-pressure water jets are usually bilateral. The injuries are mainly confined to the lower anterior portions of the eye (Bell's phenomenon). Our patient had bent forward during the accident, therefore the central and upper chorioretinal portions were also affected. Such injuries usually cause severe damage to the anterior and posterior portions of the eyes and greatly reduce visual acuity in both eyes. Because of the risk of late complications (cataract, glaucoma, retinal detachment), long-term follow-up is recommended in such patients.
