1.Study on the technical application for the vitreous humor section and removal of the intraocular foreign body by par plan
Journal of Vietnamese Medicine 1999;232(1):24-30
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.

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.

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.
