Astigmatism after extracapsular cataract extraction

Astigmatism following extracapsular cataract extraction was not studied in the literature before. An attempt was made to study the type and amount of astigmatism after extracapsular Cataract extraction. Twenty cases of cataract were operated upon using the micro-irrigation-aspiration technique adopted in Alexandria University, the same technique of incision and wound closure was used in every case. Preoperative astigmatism was measured. Postoperatively, astigmatism was measured as early as possible and then weekly for at least 6 weeks. Early post operative astigmatism was high [about 5.0 D] and was mostly of the direct type. However, it decreased gradually with time and was shifted mainly to the inverse type

Experimental herpetic keratitis in guinea pigs following corneal epithelium removal and recovery of the virus [HSV type] from different tissues

Two experiments were done. Virus was recovered from conjunctival and corneal swabs, uvea, salivary gland, lacrimal gland, trigeminal, ganglia, superior cervical ganglia, mid brain, 5th. nerve but not regained from heart blood. It was proved that guinea pigs make useful models of H.S.V. infection of the external eye
