Abstract Details

Purpose:

To show the advantages of three-part intraocular lens implantation during phacoemulsification with femtosecond assistance, complicated by lens subluxation by clinical case example.

Setting:

Orenburg branch of the S. Fyodorov Eye Microsurgery Federal State Institution, Orenburg, Russia

Methods:

Patient, 68 years old, complaints: gradual loss of vision in both eyes. Visual acuity in both eyes - finger count close to face. Objectively: narrow rigid pupil, solid core 4-5 degrees of density according to Buratto L., defect in zinc ligament fibers from 120° to 150°. Taking into account these three features, the following choice on surgical intervention tactics was made: cataract phacoemulsification with femtosecond assistance and implantation of three-part intraocular lens with haptic fixed in the ciliary sulcus, and optics - in the capsular bag.

Results:

On the 1st day - left eye UCVA 20/100, BCVA – 20/80, right eye BCVA – 20/100. Objectively: Descemet's membrane folds, corneal edema, relieved at discharge; IOL in the center, fixed, stable capsule bag; advanced posterior capsule fibrosis, reducing visual acuity. 1 month after the operation: left eye UCVA was 20/80, BCVA – 20/40, right eye BCVA – 20/100. Yag-dissection of the posterior capsule of both eyes was performed. Post-op visual acuity: left eye UCVA – 20/50, BCVA – 20/30, right eye BCVA – 20/50. The residual cause of low vision was age-related non-exudative macular degeneration of both eyes.

Conclusions:

1. Femtosecond assistance for cataract surgery, complicated by subluxation, provides: regular capsulorexis, which reduces impact on ligamentous apparatus, as opposed to manual; fragmentation of the lens core, which reduces the power and time of exposure to ultrasound during phacoemulsification. 2. Implantation of intracapsular ring redistributes the impact on lens ligamentous apparatus. 3. Implantation of three-part lens and fixing it in the abovementioned way provides: IOL stability in the capsular bag, no suture fixation of IOL, implantation through self-sealing incision of 2.2-2.4 mm.
