If the detachment is caused by a tear in the retina, the surgeon usually uses a laser or a freezing probe to spot weld the retina firmly onto the RPE and underlying tissues and thereby seal the tear. If a laser is used, this is called laser photocoagulation; use of a freezing probe is called cryopexy.
Do leg lifts. Leg lifts will strengthen and tone your thighs. Lie on the ground on your back. Slowly raise your legs until your body forms a 90 degree angle and then slowly lower your legs. Make sure that you are not using your hands to help you and that your legs are doing the work.
Once your core is strong, focus on the inner thighs, thighs (quadriceps), hamstrings, and hip flexors since these muscle need to be strong and powerful to allow for acceleration in skating, stopping, and change of direction. To train the core, use two-leg floor bridge and prone-iso abs.
