ABSTRACT
Purpose: To primarily compare surgically induced astigmatism (SIA), total and posterior corneal curvature, pachymetry, and their stabilization after 2.2 and 2.8 mm clear corneal incision in phacoemulsification. Methods: A randomized, prospective interventional study of 130 patients (130 eyes) of either sex having senile cataract (>40 years) divided randomly into two groups. The patients underwent uncomplicated phacoemulsification surgery with foldable intraocular lens implantation using 2.2 mm (group 1) and 2.8 mm incisions (group 2). The patients were evaluated preoperatively and followed?up at first, third, and sixth weeks. Results: Mean SIA was less in group 1 at all the follow?up visits which was not statistically significant (P value – 0.507 (at week 1), 0.626 (at week 3), and 0.312 (at week 6). Mean SIA decreased from week 1 to week 6 in both the groups. Both the groups showed an increase in SIA with the increase in the hardness of cataract. Posterior keratometry (k1 and k2) showed statistically significant steepening in the first postoperative week, followed by gradual flattening which continued till the sixth week postoperatively. Posterior astigmatism increased in both the groups at week 1 (not statistically significant). Thereafter, it decreases and does not change significantly after 3 weeks. Pachymetry increased significantly (P value < 0.001 in both the groups) in the first week in both the groups and thereafter stabilizing at 3 weeks. Conclusion: Reducing the incision size does not result in any significant reduction in SIA. We observed that the posterior corneal curvature majorly stabilized by 3 weeks, but some stabilization continued till 6 weeks.
ABSTRACT
A, 46‑year‑old Indian male, known hypertensive presented with left esotropia of 25 prism diopters (PD) after head injury in a roadside accident 9 months back. The deviation was constant in nature and was associated with complaints of diplopia in left lateral gaze. Traumatic sixth nerve palsy was diagnosed. The patient underwent left medial rectus recession of 5 mm and a split‑tendon transposition of the left superior and inferior recti to the lateral rectus insertion (Hummelsheim procedure). On the first postoperative day, the patient developed corneal edema and anterior chamber reaction of flare 2+ and cells 2+. The pupil was semi‑dilated and was sluggishly reacting to light. Anterior segment ischemia was diagnosed, which was managed with topical and systemic steroids.
ABSTRACT
A 60-year-old male, laborer by occupation, presented with an ulcerative lesion of medial canthus in the left eye along with infiltration and adhesion of lids to globe. He had decreased vision and restricted extraocular movements. Exenteration with skin grafting was done. Histopathologically it was diagnosed as periocular metatypical cell carcinoma with scleral infiltration. Any suspicious lesion should be diagnosed and treated early so as to prevent such extensive damage.
