All patients will undergo a 25G standard 3-port PPV with posterior vitreous detachment induction (if not already present), ILM staining with 0,25 g/l of brilliant blue-G and creation of a 360°ILM flap around the MH rim.

Phakic patients will undergo combined phacoemulsification with IOL implant in-the-bag.

In the Cover Group the ILM flap will be folded as a single layer to bridge tissue dehiscence during air-fluid exchange. All eyes will recive a mixture of 20% sulfur hexafluoride tamponade and will be instructed to position face down for 4 hours a day during the first 3 days post-operative

Phakic patients will undergo combined phacoemulsification with IOL implant in-the-bag.

In the Fill Group, multiple layers of ILM will be deliberately folded within the loss of tissue before air-fluid exchange. All eyes will receive a mixture of 20% sulfur hexafluoride tamponade and will be instructed to position face down for 4 hours a day during the first 3 days post-operative
