Reliability of a new correcting factor in calculating intraocular lens power after refractive corneal surgery.

PURPOSE: To test the reliability of a corneal radius correcting factor (R factor) in calculating intraocular lens (IOL) power in eyes that developed cataract after refractive surgery and compare it with the clinical history (CHM) and double-K (DKM) methods. SETTING: Department of Ophthalmology, Second University of Naples, Naples, Italy. METHODS: Nineteen eyes from the literature that underwent cataract extraction and IOL implantation after refractive surgery were used to compare actual postoperative and expected refractive errors utilizing the R factor, CHM, and DKM. Intraocular lens powers were calculated with 3 formulas: SRK/T, Hoffer Q and Holladay 1. The differences were evaluated with the Wilcoxon test and Spearman correlation. RESULTS: With the R factor SRK/T and Holladay 1 formulas gave the best results; 16 (84.2%) and 17 (89.5%) eyes were within +/-2 diopters (D) of emmetropia. With CHM, the best results were obtained using the SRK/T and Holladay 1 formulas; with both formulas 12 (63.2%) eyes were within +/-2 D of emmetropia. With DKM, the best results were obtained using SRK/T and Holladay 1 formulas; with both formulas 10 eyes (52.63%) were in the range of +/-2 D from emmetropia. CONCLUSIONS: The R factor can be used with the SRK/T or Holladay 1 formula because this method seems comparable or superior to DKM and CHM.

Mesalazine-associated benign intracranial hypertension in a patient with ulcerative colitis.

PURPOSE: To report a case of benign intracranial hypertension related to mesalazine use. DESIGN: Observational case report. METHODS: A 23-year-old-woman with sudden visual loss, headache, and a history of ulcerative colitis treated with mesalazine underwent ophthalmologic examination, echography, magnetic resonance imaging, and lumbar puncture. RESULTS: The examinations disclosed benign intracranial hypertension that resolved when mesalazine was discontinued and recurred when the drug was restarted. CONCLUSIONS: We recommend periodic ocular fundus examination for patients undergoing long-term therapy with mesalazine, especially if decreased vision, headaches, or neck stiffness are present, to avoid potentially severe complications of intracranial hypertension

Expulsive hemorrhage before phacoemulsification.

A 65-year-old white man who was scheduled for cataract extraction experienced a sudden increase in intraocular pressure (IOP) with flattening of the anterior chamber immediately after the anterior capsule incision. The eye was sutured, and because no decrease in pressure was noted, surgery was postponed. The presence of the cataract prevented ophthalmoscopic examination. Echographic examination revealed a hemorrhagic choroidal detachment with involvement of the ciliary body. The patient was examined regularly until the choroidal detachment disappeared 4 weeks later. He then had uneventful phacoemulsification and intraocular lens implantation.

An unusual intaocular foreign body.

An unusual foreign body in a 60-year-old man with ocular siderosis is described. A surgical needle was found in the eye after magnetic resonance imaging was performed for cerebral ischemia. As a general precaution in patients who have undergone any kind of surgery, it might be better to perform a plain x-ray before performing magnetic resonance imaging to identify such foreign bodies.
