About

By comparing the preoperative data and postoperative data of 9 patients of microspherophakia, we concluded that the 6-point transscleral suture fixation of a 3-looped haptics posterior chamber intraocular lens (PC-IOL) through scleral pockets was a feasible method of PC-IOL implantation in the surgical treatment of microspherophakia.

Inclusion criteria

  • Microspherophakia was diagnosed and lens diameter<9mm;
  • The lens subluxation was beyond the range of one quadrant and glasses cannot correct the vision;
  • Lens dislocated into the anterior chamber;
  • Lens dislocation caused elevated intraocular pressure (IOP);
  • The lens contacted the corneal endothelium;
  • Cataract;
  • Corneal endothelial cell density>1000/mm2;
  • The fundus was normal without retinal detachment, severe macular disease and optic nerve atrophy;
  • There was possible improvement in postoperative visual acuity measured by retinometer.

Exclusion criteria

  • The lens is centered and the position of the lens is stable;
  • Glasses can correct the vision obviously;
  • The reason for the elevated IOP was independent with the lens;
  • A high possibility of corneal decompensation after surgery;
  • Fundus function was poor and it is not expected to improve the vision after surgery;
  • Combined with other ocular diseases which were not suitable for IOL implantation;
  • Combined with a systemic disease that the patient cannot tolerate the surgery.

Trial design

9 participants in 1 patient group

Microspherophakia
Description:
This is a non-interventional study(NIS). All the patients diagnosed as microspherophakia are included in the study and recieved intraocular lens implantation
