Implant technology for cataract surgery has improved leaps and bounds in the last 20 years. The evolution started when the first foldable implants were developed. This allowed the implant to be inserted through a 3mm incision. Prior to that the incision needed to be enlarged to 6mm, and needed to be sutured. The foldable implant, made of silicone or acrylic, was the beginning of sutureless surgery. The next big leap was in 1997 with the approval of the first multifocal implant called Array. The multifocal lenses evolved to the ReStor,ReZoom and ReStore 3.0. The Crystalens was also introduced as the only accomodating implant. All of the lenses are designed to give a patient distance and near vision after cataract surgery. Another huge advance is the Toric implant which corrects astigmatism. Just last week it was announced that a lens that corrects distance,near and astigmatism is being used in Europe. With all this new technology it's a great time for patients who need cataract surgery.
