The advances in pars plana vitrectomy brought with it something new for the removal of the crystal clear lens or cataractous lens. Lensectomy is performed as a routine during vitrectomy or necessary if opacitification develops due to lens touch. In the present study lensectomy and anterior segment reconstruction were done in 20 cases of traumatic cataract with perforated and non perforated injuries.
| Materials and Methods|| |
In the present series 5 cases of perforated eye injuries and 15 cases of non perforated injuries with traumatic cataract were selected for lensectomy by Peyman's Vitrophage. In 5 cases of perforated injury first corneal or sclerai tear was repaired and abscission of prolapsed iris was done and in the same sitting through pars plana route lensectomy was done. For pars plana lensectomy Peyman's Vitrophage fitted in Dr. Nagpal's vitrectomy console were used.
For lensectomy incision is given 4 mm. from the limbus in upper temporal or lower temporal quadrant. Diathermy is applied to the edge of the sclerotomy in order to make it gape and expose a knuckle of uvea at least 2 mm in length and 1 mm in width. Mattress sutures are passed. A stab wound is made deep into the lens through the equator. An attempt is made with the knife to judge the hardness of the nucleus. Vitrophage tip is passed through the sclerotomy sutures and cutting is begun. The nucleus is removed within the intact bag of the lens and avoiding the anterior and posterior capsules, considerable patience is required to aspirate all the material from the periphery of the lens, after this is accomplished the anterior and posterior capsules are removed. Intra operative complication include loss of cortical material or the nucleus in to the vitreous, cortical material can be easily aspirated, while it is much more difficult to fish for the nucleus. Indirect Ophthalmoscopy is done to see the fundus after lensectomy. Then vitreophage is withdrawn, air is injected and sclerotomy wound is closed.
| Observations|| |
The age and sex incidence is shown in [Table - 1].
[Table - 2] shows the injury and the time that lapsed between injury and presentation.
[Table - 3] shows the structures involved.
Visual recovery is shown in [Table - 4]. In perforated injuries visual recovery was good because cases presented early and cataract extraction and corneal tear suturing was done in one sitting only. One case had retained foreign body with double perforation. After corneal tear repair and lensectomy indirect ophthalmology revealed retinal haemorrhage and perforation which was sealed by cryo and sclera was stitched. In perforating injury series 2 cases (40%) recovered vision 6-6 while in non-perforated series 5 cases (60%) recovered 6/6 vision.
[Table - 5] shows the visual recovery in relation to duration of injury.
| Discussion|| |
Lensectomy had its origin following the vitreous surgery where little opcification of the lens causes visualization of the vitreous cavity difficult. To overcome the problem posterior lensectomy came into existence. Also in clear lenses opacification develops due to spontaneous touch during vitreous surgery. Hence some workers  prefer lensectomy before vitreous surgery and others  prefer during vitreous surgery. We have done lensectomy in congenital cataract which prompted us to do lensectomy in traumatic cataract in perforated injury in the same sitting. It was observed that post operative visual recovery in traumatic cataract associated with perforating and non perforating injuries were fairly good. In our series in both the groups visual recovery was up to 6/6 because only lens was involved. In one case perforated injury was due to foreign body which caused double perforation of the globe, wound of entry and exit were closed and retinal tear and haemorrhages were sealed by cryo. 3 cases developed squint due to long standing traumatic cataract. It was further observed that lensectomy for traumatic cataract was easy in younger age group and in cases of recent origin. Traumatic cataract of long standing duration had hard nucleus which was difficult to remove and in one case we had to fish out from the vitreous cavity. No doubt anterior segment reconstructions and lensectomy in one sitting gives early visual recovery and prevents squint and amblyopia. If posterior segment is involved then it can be treated in the same sitting.
| Summary|| |
In the present study lensectomy and anterior segment reconstruction was done in one sitting and results were fairly good.
