For blastomere biopsy, the laser is used to drill an opening in the zona pellucida to facilitate insertion of the pipet used to remove the blastomere. For trophectoderm biopsy, the laser is first used to create an opening in the zona to promote herniation of the trophectoderm. After the trophectoderm has protruded, the laser is also used to help separate the trophectoderm cells.
