Abstract :
Context: Lens induced glaucoma due to hypermature cataract is an important cause of secondary
glaucoma. Lens induced glaucoma is a common cause of ocular morbidity.
Aims: To determine the visual outcome and study the intraocular pressure control post cataract extraction
in patients with lens induced glaucoma.
Materials and Methods: This prospective study was done in patients who underwent cataract surgery
with lens induced glaucoma visiting the Tertiary Care Centre in Latur, Maharashtra. Fifty cases of lens
induced glaucoma satisfying the inclusion criteria were selected & followed up from the time of admission
& surgery till 4 weeks post- operatively and factors influencing the final visual outcome were analysed.
Statistical Analysis used: Chi-Square test was used for comparison & p-value < 0>
statistically significant.
Results: All the cases included in the study had raised intraocular pressure on admission and 48% patients
had intraocular pressure between 30-40 mmHg. It was found that good visual acuity can be achieved in
LIG presenting within 2 weeks and IOP less than 35mmHg. Forty four percent had a best corrected visual
acuity of 6/6-6/12 post operatively. Cases (100%) having abnormal intraocular pressure on admission had
normal intraocular pressure after cataract extraction. Positive correlation between duration of symptoms
and pre op IOP to the final best corrected visual acuity was found.
Conclusions: Awareness, early diagnosis and efficient medical management can control IOP and
inflammation, with meticulous surgery and IOL implantation.
