Purpose:
To present our clinical experience using femtosecond laser-assisted cataract surgery (FLACS) and cortical cleavage hydrodissection in eyes with posterior polar cataract.
Methods:
Medical records of consecutive10 eyes of 6 patients with clinical diagnosis of posterior polar cataract (PPC), were retrospectively reviewed. All surgeries were done by using femtosecond laser-assisted cataract surgery. In all cases careful hydrodissection was done to separate the lens material from the posterior capsule.
Results:
There were 3 males and 3 females, ages 39-73 years (average 52.5 years), two of them were implanted with toric lenses. In all eyes hydrodissection was successfully performed and the lens material was separated from the lens capsule. The posterior capsule remained intact during nucleus removal in all cases. In one eye the posterior capsule broke during cortical cleaning and the tear was converted to posterior capsulorhexis (PCCC). No postoperative complications were recorded during follow-up in all eyes.
Conclusions:
Hydrodissection can be safely performed in combination (but not exclusively) with FLACS, in eyes with posterior polar cataract with no evidence of a preexisting posterior capsule rent. Hydrodissection is regarded by most surgeons as contraindicated in these eyes however apparently it is more gentile to the capsule than any other surgical maneuver and allows clean and efficient separation of the lens material from the thinned posterior capsule. Femtosecond laser capsulotomy and lens fragmentation is effective and may further assist surgery by pneumo-separation of the lens material. Anterior chamber maintainer may further aid to the stability of the chamber and safety of surgery.
