11/92. Capsular block syndrome and pseudoexpulsive hemorrhage.

    Capsular block syndrome (CBS) has been recognized as a cause of immediate or delayed postoperative accumulation of fluid behind an intraocular lens/capsulorhexis complex. Hydrodissection-related rupture of the posterior capsule may be considered a variant of CBS that can manifest intraoperatively. We describe another intraoperative situation related to CBS in which fluid loculation during hydrodissection mimics a threatened expulsive hemorrhage.

12/92. Complete capsular bag distension syndrome.

    After conventional extracapsular cataract extraction and in-the-bag intr aocular lens (IOL) implantation 3 years previously, the partially cut su perior one-third of the anterior capsulotomy flap resealed in the eye of a 55-year-old woman. With the integrity of the capsular bag restored, it distended fully; the IOL was in the center and milky fluid accumulated inside. A neodymium:YAG laser was used to drain the milky fluid and di srupt the opacified anterior and posterior capsules, restoring vision.

13/92. Oval-shaped cornea, lens duplication, and optic nerve hypoplasia associated with myelomeningocele.

    Oval-shaped cornea associated with true lens duplication and separate capsules is a rare anomaly. It can occur as an isolated finding(1,2) or be associated with other ocular and facial maldevelopments.(3-5) We report a novel association of an hourglass cornea, lens duplication, and optic nerve hypoplasia with myelomeningocele in a male infant.

14/92. Massive anterior capsule shrinkage after plate-haptic silicone lens implantation in uveitis.

    Two patients, both with bilateral uveitis, had synechiolysis, continuous curvilinear capsulorhexis (CCC), phacoemulsification, and in-the-bag implantation of a foldable single-piece plate-haptic silicone intraocular lens (IOL) in 1 eye. Several weeks postoperatively, massive anterior capsule shrinkage with obstruction of the visual axis occurred in both patients. Surgical revision was performed in both eyes. Both patients had CCC and phacoemulsification and confirmed in-the-bag acrylic IOL implantation in the second eye months after surgery in the first eye. Follow-up examinations showed no significant shrinkage of the anterior capsule opening in any eye. In patients with uveitis, intraoperative lens epithelial cell removal, creation of a large CCC, and careful selection of IOL style and material may prevent occlusion of the anterior capsule opening.

15/92. Management of atypical epicapsular star.

    An 18-year-old woman had brown pigment deposits on the central anterior capsule of the lens associated with poor visual acuity and significant anisometropia. Surgical removal of the deposits, phacoemulsification, and intraocular lens implantation resulted in visual improvement. Epicapsular stars are formed by the confluence of multiple fine pigmentary deposits. Although they cause amblyopia, this does not appear to be dense. Surgical removal of these central deposits may improve vision, even if the patient presents as an adult.

16/92. Capsular bag distention syndrome after combined cataract-lens implant surgery and Ahmed valve implantation.

    PURPOSE: To describe the capsular bag distention syndrome after combined cataract extraction with posterior lens implant and aqueous drainage device. methods: Case report. RESULTS: A persistently shallow anterior chamber and low intraocular pressure developed after combined cataract extraction with posterior chamber lens implant and Ahmed aqueous drainage device. An optically empty space between the lens implant and posterior capsule was detected 18 days after surgery. The anterior chamber deepened within minutes after Nd:YAG posterior capsulotomy. CONCLUSION: The capsular bag distention syndrome needs to be included in the differential diagnosis of shallow anterior chamber with low intraocular pressure after combined cataract extraction and glaucoma valve implant surgery.

17/92. Double-ring and double-layer sign of the anterior lens capsule during cataract surgery.

    BACKGROUND: Splitting of the lens capsule with a double-ring contour during continuous curvilinear capsulorrhexis has not often been reported. CASE: An 86-year-old woman underwent phacoemulsification cataract extraction with intraocular lens implantation in the right eye. Preoperatively, the anterior lens capsule appeared normal. OBSERVATIONS: A double-ring sign was observed during capsulorrhexis. During intraocular lens implantation, the capsule developed radial tears, and a double layer of the capsule was noted. The patient's postoperative course was uneventful. CONCLUSIONS: The findings in our patient may be uncommon and may differ from but resemble true exfoliation.

18/92. phacoemulsification in spherophakia with corneal touch.

    A phacoemulsification procedure with implantation of a foldable acrylic intraocular lens in a 31-year-old man with spherophakia is described. The procedure was necessitated by anterior dislocation of the spherophakic lens, with corneal endothelial contact and development of central corneal edema. With a careful approach, the procedure was uneventful and the outcome successful. Modern small-incision cataract surgery techniques are of great benefit in this type of complicated case.

19/92. Lensectomy in the management of glaucoma in spherophakia.

    A 42-year-old woman presented with uncontrolled glaucoma despite patent peripheral iridotomies after a previous episode of acute angle-closure glaucoma. Spherophakia was diagnosed by anterior segment findings, refraction, A-scan biometry, and ultrasound biomicroscopy. Continuous curvilinear capsulorhexis, phacoemulsification, and infusion/aspiration were performed in the right eye. Attempted intraocular lens (IOL) implantation failed, and the eye was left aphakic. Six months later, the intraocular pressure (IOP) was normal without glaucoma therapy and visual acuity was 6/6 with a contact lens. The patient then had phacoemulsification in the left eye, removal of the capsular bag, anterior vitrectomy, and insertion of an anterior chamber IOL. Four months after surgery, the uncorrected visual acuity was 6/9 and the IOP was normal without glaucoma therapy.

20/92. Surgical identification of posterior lenticonus.

    A 79-year-old patient was referred for cataract and high myopia. His optometrist noted difficult refraction. biometry predicted an emmetropic intraocular lens power of 22.0 diopters. During cataract extraction, the typical features of posterior lenticonus were noted. A careful look for posterior lenticonus is suggested in cases in which there is a discrepancy between the biometry and refraction and no significant nuclear sclerosis to account for the high myopia. Surgeons should be aware of dehiscence or thinning of the posterior capsule while doing cataract extraction in these patients.
