Abstract:

Objective  To discuss the surgical techniquesand attention points inphacoemulsification through a small pupil. Methods  Fifty-two eyes of  46  patients accepted  phacoemulsification by  using  non-cut  pupil  dilation  stop and  chop techniques.  Results  Cataract was emulsified in 47 of the 52 eyes and  the  pupil size recovered  to normal (2 to 3mm) after surgery.  In another 5 eyes,  the traction and expansion was performed after separation of synechia andexcision of the organized membranes, and pupils almost returned to round shape. The visual acuity 1 month after operation was≥0.5 in 38 eyes (73%). Conclusion  After  phacoemulsification  through a  small  pupil  by  non-cut pupildilation  method  the  pupil  can   recover  to  normal  and  the  visual  acuity  can be better recovered.
