ABSTRACT
Introduction: Cataract and vitreous opacification caused by ocular injury results in significant visual loss. Objectives: to evaluate the initial outcome of patients with ocular blunt or penetrating trauma who underwent trans pars planar vitreo-lensectomy and posterior chamber intra ocular lens insertion. Comment on the indications and applications of surgical techniques. Subjects and method: In this prospective randomized study, a total of 30 patients (30 eyes) with blunt/penetrating ocular trauma were assessed using X-ray and ultrasound in the Trauma Department of National Institute of Ophthalmology, from December 2005 to August 2006. Results: 30 patients (28 men and 2 women) with an age range from 3 to 45 years. Penetrating injuries are more common than blunt ones. The cornea is the most common site of injury (73.3%). Conclusion: Intraocular lens were implanted at the time of trans pars planar vitreo-lensectomy can provide a reasonable restoration of visual acuity and binocular function.

Background: The postoperative residual spherical equivalent (SE) refractive error of the posterior chamber intraocular lens insertion is the cause result in significant distant vision loss. Objective: The study evaluated residual SE refractive error of the patients having ocular trauma undergoing a trans pars plana vitreo-lensectomy and posterior chamber intraocular lens insertion, for recorrection of the preoperative IOL power calculated formula are also investigated. Subjects: 43 consecutive patients who underwent a trans pars plana vitreo-lensectomy and posterior chamber intraocular lens insertion in the sulcus, in the Trauma Department of National Institute of Ophthalmology, from December 2005 to June 2007. Method: This was a prospective cross-sectional study. Results: Among 43 patients, there were 39 men and 4 women, age ranged from 10 to 45 years. In the most cases, the residual spherical equivalent deviation was planned to achieve final mild myopia (mean -1.75 D by manifest refraction; -1.9 D by autorefractor measurements). The surgery could provide a best corrected visual acuity at over 0.2 (81.4%). Conclusions: Intraocular lens implantation at the time of trans pars plana vitreo-lensectomy could provide a reasonable restoration of visual acuity and binocular function. However, recorrection of the IOL power calculation was necessary in these cases.
ABSTRACT
51 eyes of 50 patients with the ophthalmological traumatic in the traumatic department of the institute of ophthalmology during 1996 - 1998 were studied. They are mainly men with ages of under 40, injuries during working. The foreign body passed over the cornea and broken the lens (62.74%). The size of the foreign body less than 3mm accounts for 70.8%. The technique of vitreous humor section though par plan was implemented under surgical microseopy for removal of the foreign body (the sucessful rate: 86.27%). The vision is generally low. The common complications were post-operative intraocular bleeding and the retinal detachment.
