title: Cataract extraction by phacoemulsification in situ and elliptical intraocular lens implantation.
abstract: OBJECTIVE
  To investigate the technique of phacoemulsification in situ for cataract extraction and elliptical intraocular lens (IOL) implantation.
  
  
  METHODS
  60 eyes of 57 cases with cataract were included and the hardness of nucleus was grade-1-2 in 25 eyes, grade-3 in 27 eyes and grade-4 in 8 eyes. Tunnel incision was made and in situ phacoemulsification with elliptical (5 mm x 6 mm) IOL implantation was performed on all the cases.
  
  
  RESULTS
  Phaco-spent-time was 45 seconds to 3 minutes 45 seconds (average 1 minute 52 seconds). Phacoemulsification in 53 eyes (88.3%) was successful in situ Visual acuities of 0.5 or better and 1.0 or better at postoperative one week were obtained in 75.0% and 56.7%, and at 1-12 month follow-up in 85.0% and 71.7% respectively.
  
  
  CONCLUSIONS
  The technique of phacoemulsification in situ and elliptical IOL implantation is worthy to be spread due to minimum postoperative astigmatism and fast restoration of visual acuity.
