This is a resident case that you really must learn from, even if you are an expert. During nucleus removal the anterior capsular rim is damaged and this break extends out to the equator of the capsular bag. How can we prevent this rip from extending to the posterior capsule?
In this case the patient is a high myope and we are implanting a +6.0 diopter lens but more importantly, the patient has a high degree of corneal astigmatism and really needs to have this toric IOL. In the USA, there are no toric IOLs which are designed for placement in the sulcus. So we really need to ensure that the rest of the capsular bag stays intact to receive this toric IOL.
The key is to prevent the anterior chamber from collapsing or depressurizing during the rest of the surgery. Then the IOL must be carefully placed in the correct position without causing stress on the capsule. Finally, viscoelastic must be removed while keeping the anterior chamber formed.
