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.

Small pupil enlargement during cataract extraction. A new method.

A new method for enlarging a small pupil during cataract extraction is described. The technique is simple and safe, and uses new instruments that reduce or entirely eliminate the need to incise or suture the iris. This method of pupil enlargement can be used for extracapsular cataract extraction and phacoemulsification procedures.

[Metipranolol in the prevention of intraocular pressure elevation after cataract extraction].

Elevated intraocular pressure during the first few days after routine intracapsular cataract extraction with and without alpha-chymotrypsin is a well-known symptom. A prospective, double-blind study was conducted to determine whether Metipranolol would prevent this increase in pressure. In 40 eyes which underwent routine, uncomplicated cataract extraction a drop of either Metipranolol 0,6% or placebo was administered before and during the first days after surgery. Prophylactic Metipranolol 0,6% can substantially reduce the incidence of severe early postoperative ocular hypertension.

[Evaluation of 200 extracapsular cataract extractions using the envelope technique].

PURPOSE: To present own results of extracapsular cataract extraction with the use of the envelope technique. MATERIAL: 200 patients (110 male, 87 female and 3 children) aged from 7 to 86 years operated in the Department of Ophthalmology in Bydgoszcz from December 1992 to May 1996, including patients with congenital, senile, presenile cataract or with diabetes. RESULTS: In 187 patients (93.5%) final distance visual acuity was 0.7-1.0. Visual acuity less than 0.7 wasn't related with surgical procedure itself. In 8 patients corneal edema, lasting for a few days, was observed postoperatively. After treatment with systemic steroids all the symptoms resolved-not effecting final visual acuity. CONCLUSION: Cataract extraction with the use of an envelope technique allows for stable IOL placement in the lens capsule and decreases postoperative corneal reaction to minimum.

Prophylactic timolol for the prevention of high intraocular pressure after cataract extraction. A randomized, prospective, double-blind trial.

Eyes undergoing routine intracapsular cataract extraction (without alpha-chymotrypsin) often experience marked ocular hypertension in the first six hours after surgery. We conducted a randomized, prospective, double-blind study to determine if timolol maleate would prevent this increase in pressure. Thirty-five eyes undergoing routine cataract extraction were given a drop of either timolol 0.5% or placebo twice before and twice after surgery. Nine (56.3%) of 16 control eyes and 2 (10.5%) of 19 timolol-treated eyes had pressures above 30 mm Hg at six hours after surgery (P less than 0.025). Thus, prophylactic timolol 0.5% can substantially reduce the incidence of severe early postoperative ocular hypertension.

Control of intraocular pressure after cataract extraction.

We carried out a prospective randomized study in 172 patients undergoing cataract extraction and lens implantation to compare the effects of pilocarpine gel, 1% acetylcholine chloride and 0.01% carbachol on early postoperative intraocular pressure (IOP), to determine the effect of sodium hyaluronate on IOP and to compare the effects of 0.01% carbachol (full-strength) and 0.005% carbachol (half-strength) on IOP, pupil size and brow ache. IOP was measured 3, 6, 9 and 24 hours after surgery, and in the full- and half-strength carbachol groups pupil size and subjective complaints of brow ache were recorded. The mean IOP 3 and 6 hours after surgery was significantly lower in all the treatment groups than in the control groups. At 9 and 24 hours it was significantly lower only in the carbachol groups. The use of sodium hyaluronate was not found to affect the postoperative IOP. There was no difference in postoperative IOP or miosis between the full- and half-strength carbachol groups, but fewer patients in the half-strength group than in the full-strength group reported brow ache at 9 and 24 hours. The results suggest that carbachol is the most effective agent currently available for the management of IOP after cataract extraction.

[Risks of cataract extraction following retino-vitreous surgery].

Extracapsular cataract extraction (ECCE) was done in 35 eyes of 30 patients after previous retinal attachment surgery with scleral buckling. A posterior chamber intraocular lens (PC-IOL) was implanted in 35 eyes. No significant modification in the cataract surgical technique was necessary.

The effects of cataract extraction on the visual field of eyes with chronic open-angle glaucoma.

PURPOSE: To investigate effects of cataract extraction and intraocular lens placement on the visual field of eyes with chronic open-angle glaucoma. METHODS: A retrospective review was conducted of 41 eyes of 41 patients with visually significant cataract and chronic open-angle glaucoma who had undergone automated static perimetry within 6 months before and 6 months after phacoemulsification with intraocular lens placement. RESULTS: Comparison of preoperative and postoperative testing showed that the mean visual acuity, foveal threshold, and mean deviation improved significantly (P < .0001), while the mean pattern standard deviation and corrected pattern standard deviation worsened significantly (P < or = .03). Eyes not receiving miotics preoperatively did not have a significant postoperative change in the mean pattern and corrected pattern standard deviations. Increasing severity of glaucoma-related visual field loss was significantly associated with less improvement in the postoperative mean deviation (P = .0001). Only two (5%) of 41 eyes had worsening of the mean deviation of 1.0 dB or greater. The foveal threshold improved more than the mean deviation did but not significantly more, except in eyes with severe visual field loss. CONCLUSIONS: Cataract extraction resulted in statistically significant improvement in visual acuity and foveal threshold in most eyes with glaucoma. In eyes with mild or moderate glaucoma-related damage, the mean deviation often improved significantly after cataract extraction, but improvement was less predictable in eyes with severe or end-stage damage. The pattern and corrected pattern standard deviations may be reliable indicators of glaucoma-related damage in eyes with cataract but without constricted pupils.

[Use of beta adrenergic blockaders in the prevention of vitreous body prolapse in cataract extraction].

To prevent vitreous body prolapse in cataract extraction, intraocular pressure is reduced by means of beta-adrenoblockers instillation (timolol 0.5% solution) in the evening and 2 hours before surgery in the morning. Intraocular pressure was followed up in 59 patients with senile and 12 with complicated cataract subjected to cataract cryoextraction by the same surgeon. The pressure decreased by 5.6 +/- 1.3 mm Hg. Prolapse of the vitreous body occurred in 1 case.
