    Most patients (83.5%) maintained an intact posterior capsule after cataract surgery. However, 35% experienced opacification within three years, a rate unaffected by capsule polishing.

    Area of Science:

    • Ophthalmology
    • Surgical Science

    Background:

    • Senescent cataracts are a common cause of visual impairment.
    • Phacoemulsification is a standard surgical technique for cataract removal.
    • Posterior capsule opacification (PCO) is a frequent complication after cataract surgery.

    Purpose of the Study:

    • To evaluate the incidence of posterior capsule opacification after phacoemulsification.
    • To assess the effect of posterior capsule polishing on PCO.
    • To report the safety and efficacy of secondary capsulotomy for PCO.

    Main Methods:

    • A series of 200 consecutive senescent cataracts were treated with phacoemulsification.
    • Posterior capsule integrity was assessed post-surgery.
    • Patients were followed for the development of opacification.

  • Posterior capsule polishing was performed in some cases.
  • Secondary capsulotomy was performed using the Haab discission knife in 56 cases.

    • Main Results:

    • 83.5% of patients had an intact posterior capsule initially.
    • 35% of patients developed posterior capsule opacification.
    • The incidence of opacification reached 50% in patients followed for over three years.
    • Posterior capsule polishing did not prevent or delay opacification.
    • Secondary capsulotomy was performed without direct complications.

    Conclusions:

    • Posterior capsule opacification is a significant long-term complication following phacoemulsification.
    • Posterior capsule polishing is not effective in preventing PCO.
    • Secondary capsulotomy is a safe and effective treatment for visually significant PCO.
