This 42 year old patient sustained an airbag injury to his face a few months ago. He noted cloudy vision in his left eye, which has since worsened. He is seeing you for consultation and the view is shown in this picture.
His right eye is completely normal and sees 20/20. The left eye has vision of Count Fingers at 1 meter. There is no afferent pupillary defect. The pressure is 19 mmHg in the left eye and gonioscopy shows a normal angle without evidence of damage. The left cornea is clear and has a normal endothelial cell count and pachymetry. The pupil does not dilate despite maximum topical mydriatic medicines. The lens shows a whitish cataract with nuclear and cortical changes. There is a large area of posterior synechiae with three clock hours of iris adherent to the anterior lens capsule. There is a very hazy view of the posterior segment but the B-scan ultrasound looks reasonable without any gross abnormalities.
What is your approach for the cataract surgery?
Before you answer, let me show you one more photo taken at the slit-lamp microscope:
This photo shows that there is a large gap between the superior iris and the lens. When we place the patient in the supine position with the iris parallel to the floor of the room, we look using the indirect ophthalmoscope and the crystalline lens tilts back deeper into the vitreous cavity. It appears that the only thing holding the cataract in place is the area of posterior synechiae.
Now what is your approach?
My approach was to send the patient to a trusted vitreo-retinal colleague who performed a pars plana vitrectomy and pars plana lensectomy. He also noted a small area of rhegmatogenous retinal detachment which he repaired. Finally, an acrylic IOL with four loop haptics (B&L Akreos AO60) was secured to the sclera with Gore-Tex.
Sometimes, the best surgical approach is referring the patient to a colleague.
