Extracapsular cataract extraction and primary posterior chamber lens implantation.

We reviewed the charts of 420 consecutive extracapsular cataract extraction cases in which the surgeon's primary intention was to implant a posterior chamber lens. Posterior chamber lens implantation was precluded in eight cases (1.9%) because of vitreous loss or capsule dehiscence. A visual acuity of 20/40 or better was achieved by 83.8% of patients. When nonoperative causes of poor vision were eliminated, this result was achieved by 96.7% of patients. The percentage of patients achieving 20/40 or better acuity decreased with increasing age but remained constant despite varying follow-up periods. The most common complication was opacification of the posterior capsule, occurring in 25.7%; 83.8% of the complications occurred during the first two postoperative years. We conclude that extracapsular cataract extraction with primary posterior chamber lens implantation is an efficient way to restore good vision after cataract formation and that the results appear to remain stable over time.

Phacoemulsification with the Heslin/Mackool Ocusystem: a follow-up report.

The experience of one surgeon (KBH) with phacoemulsification and the Heslin/Mackool Ocusystem is reported. In a study involving 350 cases with a mean follow-up period of 20.1 months, 88.6% of the patients achieved a visual acuity result of 20/40 or better, and when nonoperative causes of poor vision were eliminated, 97.2% of the study group achieved such a result. The most common complication cited was opacification of the posterior capsule, occurring 20.0% of the time. The authors conclude that the Heslin/Mackool Ocusystem is a safe and efficient instrument for phacoemulsification.

Clinical retrospective study comparing planned extracapsular cataract extraction and phakoemulsification with and without lens implantation.

We conducted a clinical retrospective study in which the records of 350 consecutive extracapsular cataract operations were reviewed in order to compare two cataract extraction techniques: planned extracapsular cataract extraction (PECCE) and phakoemulsification (PKE) with and without intraocular lens implantation. The patients in the PKE group experienced significantly better vision overall. However, when an adjustment was made for the difference in age between patient populations there was no significant difference in the percentage of patients achieving good vision between the two groups. Similarly, there was no statistically significant difference in the total number of operative or postoperative complications. The patients in the PKE group required less time for refraction to stabilize and averaged less postoperative astigmatism. Both of these differences were statistically significant even after an adjustment was made for the difference in age between populations. The presence or absence of an intraocular lens had no effect on the findings.

Phacoemulsification with the Heslin/Mackool Ocusystem: results of a retrospective study.

One surgeon's experience with phacoemulsification and the Heslin/Mackool Ocusystem is reported. The visual results and intraoperative and postoperative complications are comparable to those reported by surgeons using other phacoemulsification instruments. The authors conclude that the Heslin/Mackool Ocusystem is an efficient instrument for phacoemulsification.

Combined phacoemulsification and closed pars plana vitrectomy capability in a single computerized instrument.

The Heslin/Mackool Ocusystem allows either phacoemulsification or pars plana vitrectomy in a maximally controlled closed system. A unique flow control system maintains a constant balance between infusion and evacuation. Low flow rates and high suction levels are therefore possible without surging of intraocular contents or ocular collapse. The ultrasonic handpiece has reusable tips and is air-cooled, self-tuning, lightweight and autoclavable. The vitrectomy handpieces have a guillotine cutting mechanism or a self-sharpening rotational cutting mechanism and are as small as 0.79 mm in diameter (21 gauge). One and two-handed techniques for phacoemulsification and vitrectomy are possible through limbal or pars plana approaches.
