The Efficacy of a 6-point Transscleral Suture Fixation of a 3-looped Haptics PC-IOL Implantation Through Scleral Pockets for Surgical Management for Microspherophakia

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.
