A Clinical Study on Implantation of Anterior Chamber Intraocular Lens and Posterior Chamber Intraocular Lens by Scleral Fixation in Eyes without Capsular or Zonular Support

The study was performed retrospectively to compare the results of anterior chamber IOL(Intraocular Lens) implantation and posterior chamber IOL implantation by scleral fixation in cases of inadequate zonular or capsular support during the extracapsular cataract extraction. A total of 27 cases were reviewed of which 11 cases had anterior chamber IOL implantation and 16 cases had posterior chamber IOL implantation by scleral fixation. The follow-up period ranged from two to twenty-four months. Nine of eleven in anterior chamber IOL group and thirteen of sixteen in posterior chamber IOL group had the final corrected vision of 0.5 or better. Vision-threatening complications included two cases of cystoid macular edema in anterior chamber IOL group, whose visual acuity was 0.1 and 0.5, and three cases of vitreous hemorrhage in posterior chamber IOL group, which had little effect on visual outcome The final visual acuity didn't show statistically significant difference between the two groups.

The Effects of Tenzel Operation on Cicatricial Entropion

Tarsus wedge resection and lid margin splitting with recession. Tenzel operation, were performed for cicatricial entropion of seventeen eyelids in twelve patients. The ages ranged from 10 to 68 years(mean, 45.1 years). Seven patients were women and five patients were men. The causes of entropion were chemical burn, thermal burn, ocular pemphigus and previous lid operations All patients were satisfied with good cosmesis, functional results without recurrences and improvement of tearing, ocular pain and photo-phobia after the follow-up period of 3 to 36 months. The advantages of Tenzel operation over other methods were simplicity, excellent cosmetic and functional effects and less recurrence. Therefore, Tenzel operation is recom mended as the method of choice for cicatricial entropion.
