Comment on: Relative efficacy of intracameral moxifloxacin injection methods

Abstract

The reasons for dividing the lens nucleus into 8 sections are as follows: first, to decrease phacoemulsification time and cumulative dissipated energy; second, to decrease volume and facilitate movement out of the lens capsule; and third, to ensure holding with the ultrasound tip and minimize contact with the corneal endothelial cells. These 3 are considered effective regardless of the hardness of the lens nucleus. Therefore, there is no need to change the number of segments according to the hardness of the lens nucleus. Moreover, it is not possible to divide the lens nucleus into 6 sections by dividing it in the center. Furthermore, it is difficult and impractical to divide the lens nucleus into more than 8 segments. Division into 8 segments is the optimal solution for cataract surgery.The size of the continuous curvilinear capsulorhexis and the corneal incision has been well discussed in my paper.I would like to thank Dr. Yeoh for giving me the opportunity to explain the reasons many ophthalmologists have abandoned the prechop technique and to emphasize that the 8-chop technique is a safe and efficient cataract procedure that can be used successfully in both normal and difficult (grade IV to V) cases. I would also like to stress that there are no inaccuracies in my paper. 2 Only when ophthalmologists truly understand the 8-chop technique, will they be able to perform the Lance-chop technique on grade IV to V lens nuclei. Explanations of the 8-chop technique can be found through the 8-chop channel on YouTube.
