Aspergillus niger endophthalmitis after cataract surgery.

We report a 65-year-old diabetic woman who developed Aspergillus niger endophthalmitis after cataract surgery. She presented 9 weeks after extracapsular cataract extraction with a black growth covering the cornea and moderate echoes in the vitreous on ultrasonography. After microbiological confirmation of fungal endophthalmitis, the patient received intravitreal amphoterecin B 5 micro g, topical natamycin 5% hourly, atropine 1% 3 times, and oral antifungal therapy. The patient was told the visual prognosis and was advised to have penetrating keratoplasty and vitrectomy, which she refused.

Phacoemulsification in patients with Fuchs' heterochromic uveitis.

PURPOSE: To evaluate the results of phacoemulsification with capsular bag fixation of a poly(methyl methacrylate) (PMMA), acrylic, or silicone intraocular lens (IOL) in patients with complicated cataract resulting from Fuchs' heterochromic uveitis (FHU). SETTING: Department of Ophthalmology, Postgraduate Institute of Medical Education and Research, Chandigarh, India. METHODS: This study evaluated 20 eyes of 19 patients with FHU and cataract who had uneventful phacoemulsification with endocapsular implantation of an IOL and completed a 1-year follow-up. RESULTS: Preoperatively, loss of the iris collarette and fine keratic precipitates were seen in all 20 eyes, iris heterochromia in 16, iris atrophy in 12, and iris nodules in 2. Fourteen eyes had mild or negligible preoperative anterior chamber inflammation. No eye had increased intraocular pressure. An acrylic IOL was implanted in 10 eyes, a silicone IOL in 4, and a PMMA IOL in 6. There were no significant differences in outcomes among the 3 IOL groups. Three patients had intraoperative hyphema that resolved spontaneously. Postoperatively, 16 eyes had mild anterior chamber reaction. Four patients had significant anterior chamber inflammation necessitating the use of frequent topical steroids. No case had secondary glaucoma or posterior synechias. The best corrected visual acuity was 6/5 in 6 eyes, 6/6 in 11, and 6/9 in 3. CONCLUSIONS: Uneventful phacoemulsification with endocapsular IOL implantation visually rehabilitated patients with FHU. All 3 IOLs yielded similar results except for increased early postoperative inflammation and late dense anterior capsule opacification in the silicone group. Further studies comparing the outcome of different IOL materials are required to determine their effectiveness in patients with FHU.

Comparison of the thermal effect on clear corneal incisions during phacoemulsification with different generation machines.

BACKGROUND AND OBJECTIVE: Older generation phacoemulsification units are widely employed where economics do not permit frequent upgrades. Thermal effects on the cornea while performing phacoemulsification with different generation machines were evaluated. PATIENTS AND METHODS: The thermal effect on the clear corneal incision during uncomplicated phacoemulsification performed by the Series 10,000 (Alcon Laboratories, Fort Worth, TX) and the Diplomax (Allergan, Irvine, CA) machines was clinically evaluated and correlated with the effective phacoemulsification time required. The clinical outcome was analyzed with respect to wound closure and surgically induced corneal astigmatism. RESULTS: The average effective phacoemulsification time required to emulsify a grade IV cataract was 88.33 +/- 15.81 seconds with the Series 10,000 machine and 61.67 +/- 21.79 seconds with the Diplomax machine. A grade 2 or more thermal effect was seen in 19.33% of patients operated on with the Series 10,000 machine and 3.22% of patients operated on with the Diplomax machine. The resultant tissue retraction affected wound closure and mean surgically induced corneal astigmatism (1.71 +/- 1.05 D with the Diplomax machine and 2.21 +/- 1.32 D with the Series 10,000 machine). CONCLUSIONS: Newer generation machines require less phacoemulsification power to emulsify hard cataracts, and the clinical outcomes are more favorable. Incision burns must be kept in mind when working with older generation phacoemulsification machines.
