I.O.L. either primary or secondary has proved to be useful after traumatic cataract extraction. Problem of binocular single vision will be better solved and the traumatic eye becoming divergent and amblyopic can thus be avoided.

| Introduction|| |
Man is subjected to accidental trauma in various ways and this may happen to any individual at any age. Young people seem to be more vulnerable. Ocular trauma often leads to traumatic cataract along with damage to other ocular structures. In cataract the lens needs removal and the problem of uniocular aphakia sets in. In most of these cases the other eye remains normal with 6/6 vision. Spectacle correction does not help in developing binocular vision and contact lenses are helpful to a certain extent only. These aphakic eyes usually remain unaided and over the years become divergent and amblyopic. With improved technology and increasing popularisation of intraocular lenses the time has come when I.O.L. can be used after the extraction of a traumatic lens. The problems of binocular vision will be solved and thus we can prevent the traumatic eye from becoming divergent and amblyopic. With this thought I.O.L. has been placed after extraction of the traumatic lens in this series.
| Materials & Method|| |
Fourteen cases of traumatic cataract having 6/6 vision in the other eye were treated as shown in [Table - 1], four of them had penetrating injury, while repairing the corneal wound the traumatic lens. was removed in all the cases. A secondary I.O.L. was implanted when the eye had become quiet. In the other cases the traumatic lens was removed and an I.O.L. was introduced as a primary procedure. All these were A.C lenses.
| Discussion|| |
R, Kern  et all reported their experience with 24 cases of traumatised eyes in children where I.O.L. was introduced. In 19 of them visual recovery was good. J.L.Menezu  et all successfully treated 75 cases of unilateral trauumatic aphakia with I.O.L, they observed disappearance of exotropia in several cases after insertion of the lens.
A. Momose  has treated 36 cases of traumatic cataract with I.O.L. over the years.
Nahata  et all in their I.O.L.series have 8 cases of traumatic cataract.
D. Singh  et all introduced I.O.L. in 113 cases of traumatic cataract belonging to different age groups.
R. Srinivasa  et all had good visual recovery in 12 cases of traumatic cataract after treating them with I.O.L.
In this series 14 cases of traumatic cataract belonging to the age group of 8-23 years were implanted with I.O.L. The visual recovery as shown in [Table - 2] is encouraging. Three patients had 6/9 vision, two of them had 6/12 vision and 6/18 vision was obtained in 3 cases.
[Table - 3] shows that in some cases trauma had damaged the posterior segment resulting in macular scar and vitreous haze. Corneal scar was also responsible for poor visual recovery. In case no. 11 while introducing the lens reconstruction of the pupil was done as a corneal scar was obstructing the pupil. He obtained 6/60 vision. In three cases (Group III) the eye had become divergent after the trauma as I.O.L. was given 2 years after the trauma. These eyes remained divergent even after introduction of I.O.L. though there was visual improvement.
In other cases, which had received an I.O.L. within a few months of developing the cataract after the trauma, the eye remained straight.
| Conclusion|| |
Six months to three years follow up has revealed promising results and a long term follow up will evaluate how the traumatic eyes behave with I.O.L. in the long run. Young people including children have also been given I.O.L's. A long term follow up will be able to give us the answer to the need of I.O.L. in uniocular aphakia following trauma. It is also observed that timely operation and introduction of I.O.L. will save the eyes from becoming divergent. The good results however make us confident to use I.O.L's for more physiological rehabilitation.
