ABSTRACT
Evaluation of the value of Acrylic IOLs in minimizing the rate of posterior capsule opacification [PCO] in pediatric age group in comparison to PMMA IOLs. This study included 37eyes of 29 patients with congenital, developmental or traumatic cataract, with a mean age 6.54 +/- 1.90 years, and 68.97% of them were males. The mean of the follow up period was 17.72 +/- 4.32 months. Patients with any associated ocular or systemic disease were excluded from the study. The study group was divided into 2 subgroups; the first group was implanted with Acrylic IOL [21 eyes,.] while the second group was implanted with PMMA IOL [18 eyes]. Statistical analysis of the BCVA, rate of development of PCO and the onset of its development were done. In both groups, there was statistically significant improvement of the visual acuity postoperatively; but the BCVA was significantly better in the first group than in the second group. The rate of development of PCO dense enough to affect the visual acuity was significantly lower in the group of patient implanted with Acrylic IOLs [28.57%] compared to the group implanted with PMMA lenses [4 7.62%]. At the same time, the onset of development of PCO was significantly earlier in the PMMA lenses than in the Acrylic IOLs [5.14 +/- 2.91 months and 8.40 +/- 4.40 months respectively,]. Pediatric patients implanted with Acrylic IOLs have less incidence of clinically significant PCO than patients implanted with PMMA IOLS. Also, the posterior capsule remains clearer for a longer- period of time with the Acrylic lenses. However the long terms effects of Acrylic IOLs in children whose life expectancy is much more are yet to he assessed

This study aimed to investigate the efficacy of the sub-Tenon's anaesthesia as a method of local anaesthesia in phacoemulsification operation. 92 eyes of 72 Patients admitted for phacoemulsification surgery were included in this study Our patients were divided into 2 subgroups; the first group was operated upon by using sub-Tenon's anaesthesia while the second group was operated upon by using peribulbar anaesthesia. We evaluated the pain during injection, intraoperative pain, degree of akinesia, complications related to the anaesthesia, and the overall surgeon comfort, The group of the sub-Tenon's anaesthesia had significantly less pain score during injection of the anaesthesia. On the contrary the intraoperative pain score was higher in the sub-Tenon's group, but the difference was statistically insignificant. Also, the akinesia was significantly less in the sub-Tenon's anaesthesia group, but it did not affect the overall surgeon comfort during surgical steps or caused any increased risk to the patient. Sub-Tenon's anaesthesia is a simple and safe procedure that can be used efficiently in the ophthalmic surgeries. It gives low pain score during injection and effective intraoperative analgesia. The problem in this technique is the limited akinesia compared to the peribulbar anaesthesia, but this residual degree of eye movement does not interfere with continuing the surgical steps of the operation subsafely and comfortable. More investigation on a wider scale needed to insure the efficacy of this type of local anaesthesia

Evaluation of the short-term effect of topical 2% cyclosporine A [CsA] freshly prepared in artificial tears for treating patients with severe vernal keratoconjunctivitis [VKC]. Our study included 21 patients with severe VKC for at least 1 year and not responding to topical steroids treatment. The study group had a mean age of 11.29 +/- 2.43, and 71.43% of them were male. The eyes were categorized into 2 subgroups, the first up included the right eyes and the second group included the left eyes the whole patients in the study group. CsA freshly prepared in artificial tears was used in the right eye while placebo was used in the other eye. Statistical comparison between the grade of the symptoms and signs in both subgroups was done. Statistically signifiicant improvement in the symptoms and signs of VKC in the eyes treated with CsA compared to the eyes treated with placebo was observed. No major side effects from the drug were encountered, During the follow up period, the eyes were stable and needed only simple drops to control the condition except in 3 patients that needed steroids eye drops again. Topical 2% CsA in artificial tears is both effective and safe in alleviating signs and symptoms of patients with severe VKC. It can act as a steroid sparing agent in these cases to minimize the need for topical steroids. However the long-term follow up is needed to answer a lot of questions about the drug
