The effect of phacoemulsification through a small pupil and intraocular lens implantation

Objective To observe the clinical effect of phacoemulsification through a small pupil and intraocular lens implantation.Methods Forty-two eyes of 38 patients accept phacoemulsification with intraocular lens implantation in treatment of small pupil cataract patients.Among them,14 eyes with posterior synechia after glaucoma surgery,6 eyes with small pupil caused by trauma,4 eyes without complications (All of the patients age≥71).After glaucoma surgery by using foldable IOL implantation with clear corneal incision,26 eyes implanted heparin surface modified intraocular lens with straight scleral tunnel incision,other 2 eyes implanted foldable lens.Postoperative follow-up 1-3months.Results The number of the preoperative uncorrected visual acuity (UCVA) or best-corrected visual acuity (BCVA) ≤ 0.3,Postoperativerly,the UCVA or BCVA ≥0.6 after the first week and first monthe were achieved in 31 eyes(73.8％)and 34 eyes(81.0％) ＞0.8 were achieved in 19 eyes(45.2％) after the first week.the pupil nearly circular or oval were achieved in 36 eyes,irregular pupil were achieved in 6 eyes.Part of the patient's pupil is larger in diameter than the preoperative.Conclusion The operation of phacoemulsification through a small pupil and intraocular lens implantation is complicated,prevention and treatment of the complications is very important.
