Aim: To describe a new diagnostic sign and improved technique for cataract extraction in cases with posterior lenticonus.
Setting: Kasr Alainy hospital, Cairo University, Cairo, Egypt
Methods: A consecutive series comprised of 16 eyes of 15 patients with definite or suspected posterior
lenticonus were diagnosed and surgically treated by a modified technique to prevent premature opening of posterior capsule
Results: The posterior cone can be seen in early cases, but is obscured by the cataract in advanced cases. We have recognized irregular posterior opacity as a sign of posterior lenticonus. Our technique for cataract extraction prevented premature opening of posterior capsule.
Conclusion: Recognition of posterior lenticonus is key for uncomplicated cataract removal in these cases. We describe a new sign and a new technique to manage posterior lenticonus safely.
